For years, most conversations about AI training jobs focused on text. Contributors wrote prompts, checked chatbot answers, and evaluated whether a model followed instructions.
That work hasn’t disappeared. But an increasingly interesting part of AI evaluation involves listening to generated voices, examining pictures, and watching short videos.
Instead of deciding which paragraph reads better, a contributor might judge whether speech sounds natural, whether an image actually matches a request, or whether a video changes objects in ways that make no physical sense.
It is called multimodal AI evaluation, and it opens up a different set of tasks for people who are good at observing details and explaining what they notice.
This isn’t a promise of effortless income. Projects have screening requirements, rates vary by location, and assignments may not always be available. Still, understanding this work can help you decide whether it’s worth exploring.

AI training is no longer only about words
A multimodal AI system can process or produce more than one type of information, such as text, images, audio, or video. A model might describe a photograph, talk with someone using a synthetic voice, or create a short video from a written prompt.
Each new capability brings a new question: Does the result actually work for the person using it?
An attractive image can contain the wrong number of objects. A realistic voice may mispronounce an important name. A video can look convincing frame by frame but show an object changing shape halfway through.
These are the kinds of details human evaluators may be asked to investigate. Depending on the project, contributors compare two outputs, give rubric-based scores, describe errors, or explain why one result better satisfies the original request.
OpenAI’s guide to image evaluations emphasizes that visually impressive results may still fail requirements involving exact text, object counts, or changes to the wrong part of an image. Its voice-agent evaluation guidance similarly distinguishes natural-sounding conversation from completing a user’s task.
Inside an audio evaluation task
Audio work can involve generated speech, conversational assistants, transcription, accents, or the relationship between a spoken request and the response that follows.
Imagine listening to two AI voice assistants answering the same question. Both give the correct information. One sounds clear and conversational; the other repeatedly pauses in unnatural places and mispronounces a familiar word.
An evaluator may need to rate:
- Intelligibility: Can the listener understand the words?
- Naturalness: Do rhythm, emphasis, and pauses resemble ordinary speech?
- Accuracy: Was the spoken information correct?
- Conversation quality: Did the voice answer the actual question and respond appropriately?
- Consistency: Did pronunciation, volume, or vocal style change unexpectedly?
Some projects involve live, scenario-based conversations rather than listening to prerecorded samples. That can require a quiet space, headphones, a microphone, and the ability to speak clearly while making observations.
Practice example: The airport announcement
Illustrative task, not an actual platform assessment.
Two voice models read: “Flight 218 to Delhi is now boarding at Gate 16.” Model A reads the sentence clearly but places a slightly unusual pause before “Gate 16.” Model B sounds expressive but says “Gate 60.”
If the rubric prioritizes factual accuracy, Model A should rank higher. The wrong gate number is a meaningful information error, even if Model B sounds more natural. A useful explanation identifies both the decisive error and the secondary quality difference.
That is an important part of evaluation: the best-sounding result is not necessarily the best.
Inside an image evaluation task
Image evaluation requires more than choosing the picture you find attractive.
A project might show two images generated from the same prompt and ask which follows the instructions more closely. The evaluator may inspect object counts, spatial relationships, realism, spelling, lighting, or whether an edit preserved everything that was meant to stay unchanged.
For instance, a request could ask for a product photograph featuring three blue bottles against a white background. One result might have beautiful lighting but include four bottles. The other might be less stylish but meet the exact quantity, color, and background requirements.
The appropriate choice depends on the scoring rubric. If the number of objects is mandatory, the first image fails a clear constraint.
Practice example: The café sign
Illustrative task, not an actual platform assessment.
Prompt: “Create a realistic photograph of a café storefront. The sign must read ‘OPEN DAILY,’ and the door must be green.”
Image A has a green door and convincing street photography, but its sign reads “OPEN DALLY.” Image B has slightly less realistic lighting but correctly displays “OPEN DAILY” above a green door.
An evaluator should flag the text error in Image A and favor Image B when instruction accuracy is the priority. A strong written explanation names the specific misspelling instead of saying only that the image “looks wrong.”
The same principle applies to photo editing. If the task asks AI to change a jacket color, an evaluator may need to confirm that the face, background, and rest of the clothing remain unchanged.
Video evaluation adds a problem that still images don’t have
Video introduces time. A model must maintain consistency from one frame to the next.
A generated clip may appear believable at first, only for a person’s hand to change shape, a ball to move in an impossible direction, or a parked vehicle to disappear between frames. Other problems include inconsistent lighting, unnatural body movement, abrupt scene transitions, or speech that doesn’t match lip movement.
Evaluation can involve replaying clips, slowing down key moments, or comparing two versions against a prompt. Contributors may be asked to explain not only which video is better but when the error occurred.
Practice example: The bicycle clip
Illustrative task, not an actual platform assessment.
Prompt: “Generate a five-second video of a cyclist riding past a red mailbox on a sunny street.”
Video A keeps the cyclist’s movement smooth, but the red mailbox disappears halfway through the clip. Video B contains slightly awkward pedaling but keeps the objects in the scene consistent.
A useful evaluation would identify the disappearing mailbox in Video A and the unnatural movement in Video B. Which clip ranks higher depends on whether the rubric gives greater weight to scene consistency or movement quality.
This is why “looks realistic” isn’t enough as an evaluation comment. You need to point to the evidence.
Research shows how difficult visual judgment can be for AI
There is a good reason that visual reasoning continues to receive research attention.
In October 2026, Scale AI and Elorian introduced Humanity’s Sixth Sense, a benchmark with 522 tasks built around photographs and video clips. The questions examined things people often infer quickly, such as physical relationships, likely events, and social context.
Human participants achieved 93.1% accuracy in the reported evaluation. The strongest model in the initial research reached 53.6%.
Those numbers deserve context. They describe performance on one deliberately challenging benchmark, not AI performance on every visual task. The study also focused on image and silent-video reasoning, not audio evaluation, and it does not establish how many contractor jobs are available.
What it does illustrate is that a system can recognize visible objects yet struggle to understand what a scene implies. Evaluators who notice these gaps can help researchers measure where models still fall short.
Is this work suitable for beginners?
Some media-evaluation opportunities prioritize fluent language skills, clear explanations, patience, and attention to detail rather than advanced programming.
One publicly advertised Outlier opportunity describes work involving conversations with AI voice models and side-by-side comparisons of generated images and videos. It also emphasizes careful replaying, spotting errors, and writing original explanations.
That doesn’t mean anyone can sign up and immediately receive work.
Outlier’s general FAQ currently says contributors need at least an associate degree, with higher qualifications required for some projects. Individual listings may specify their own experience, preferred qualifications, locations, and screenings. A particular referral campaign describing broad eligibility should not be read as an exemption from every applicable platform rule.
Depending on the assignment, you may also need:
- Strong written English or another required language.
- A reliable computer and internet connection.
- Headphones and a quiet environment for audio tasks.
- The ability to explain judgments using specific visual or audio evidence.
- A willingness to follow detailed scoring rubrics consistently.
Previous experience in editing, language review, quality assurance, photography, audio production, or video work may be useful, but it is not a substitute for meeting the stated requirements.
How much can you earn evaluating images, audio, and video?
There isn’t a universal multimodal-evaluator hourly rate.
For a concrete example, one Outlier English media-evaluation listing advertised up to $15 per hour for core project work, while its page also displayed an “up to $18/hour” headline that included potential additional compensation. Rates varied by country, expertise, and project requirements.
That should be read as a listing-specific advertised amount, not the average pay for the industry or a rate that everyone is offered.
Projects may pay hourly or per task, and available work can change. You may also spend time screening, reviewing project instructions, doing quality checks, or waiting between assignments. Before accepting a project, confirm which activities are paid and whether any task-completion or quality conditions apply.
A rate of $15 per payable hour is not the same as earning $15 for every hour devoted to the opportunity. Our guide on AI training pay explains the difference between advertised compensation and actual earnings.
Where to look for multimodal AI evaluation work
For this specific type of opportunity, Outlier is a relevant platform to explore because it has advertised audio, image, and video evaluation work. The link leads to a referral-based application path, not a promise of an active assignment or guaranteed acceptance.
Other AI training platforms may periodically recruit people for media-related projects, but you should verify the current work category before applying. A platform offering text evaluation or general data annotation is not automatically recruiting video evaluators.
Our AI training platform comparison provides a broader starting point for finding legitimate contractor platforms.
Look for role descriptions mentioning image evaluation, video evaluation, speech quality, audio annotation, multimodal AI, voice model evaluation, or media quality assessment. Search terms are more reliable than assuming every role titled “AI trainer” involves the same tasks.
A simple way to prepare before applying
If this field interests you, practice writing short, evidence-based comparisons.
Start with public-domain or self-created media that you have permission to use. Write a specific prompt, compare two hypothetical outputs or your own test samples, and record whether each meets the requirements.
Try this four-part format:
- State the requirement. What was the AI supposed to produce?
- Describe the observation. What exactly did you see or hear?
- Explain the significance. Is it a factual error, instruction failure, or minor quality issue?
- Make the judgment. Which result best meets the rubric, and why?
For example, “Video A is better because the object remains consistent throughout the clip, whereas the same object disappears at 00:03 in Video B” is more useful than “Video A is more realistic.”
Follow platform rules when taking an actual assessment. If independent work is required, don’t use AI tools to generate your answers. Avoid uploading private recordings, copyrighted client material, or other content you are not authorized to share.
A different kind of AI training opportunity
Multimodal AI evaluation is easy to overlook if your picture of AI training is limited to prompts and chatbot responses.
The work can involve attentive listening, spotting an incorrect word on a sign, identifying inconsistencies in moving images, or judging whether an assistant actually understood a spoken request. Some tasks are accessible to strong generalist reviewers; others require specialized skills.
The most useful first step isn’t chasing the largest advertised hourly rate. It’s understanding which type of evaluation matches your strengths, checking eligibility, and learning to explain what you observe with precision.
As AI becomes more capable of generating sights and sounds, that ability to make careful human judgments remains an important part of measuring its quality.
