Evaluate MOSI Intelligence’s MOSS-Audio and Qwen2-Audio for drafting descriptions of a recorded performance’s pace, tone and emphasis. Keep the result grounded in audible delivery and have a voice director approve it. A description of how a line sounds should not become a claim about the performer’s private emotional state.

## Compare speech-description candidates

| Candidate | Documented basis | What the voice team must verify |
| --- | --- | --- |
| [MOSS-Audio Instruct](https://huggingface.co/OpenMOSS-Team/MOSS-Audio-8B-Instruct) | Speech captioning and analysis of vocal characteristics | Useful, localized descriptions of delivery |
| [Qwen2-Audio-7B-Instruct](https://github.com/QwenLM/Qwen2-Audio) | Speech and audio analysis, with emotion-recognition evaluation | Whether answers describe the actual performance rather than the script alone |

MOSS-Audio is a relevant MOSI starting point when the production team wants descriptive speech review within an audio-understanding workflow. These documented tasks do not prove reliable word-specific emphasis detection or an objective interpretation of tone. Test those fields directly.

## Define a vocabulary directors can use

Separate pace, vocal texture, intonation, emphasis and perceived tone. “Fast” describes pace; “breathy” describes texture; “reassuring” is an interpretation that needs context. A useful note can say where the delivery changes without pretending that every adjective is an acoustic measurement.

| Note dimension | Useful review question |
| --- | --- |
| Pace | Is the delivery steady, accelerating or slowed at a particular phrase? |
| Pauses | Where does a pause affect the meaning or flow? |
| Emphasis | Which word or phrase is perceptually prominent? |
| Intonation | How does the contour shape the line? |
| Perceived tone | What interpretation is supported, and how uncertain is it? |

Use descriptions that permit verification. “The final phrase slows” is easier to check than “the speaker becomes completely sincere.” Leave the performer’s intention to the production context and director.

## Compare the same words in different performances

Build an audition set with the same script delivered in contrasting ways, plus different scripts with similar delivery. Include neutral narration, a restrained dramatic reading, a question and a line with shifted emphasis.

Have directors annotate the recordings before seeing model output. Then check whether the description changes when the performance changes. A system that calls every positive sentence “cheerful” may be responding to word meaning rather than the sound.

Include quiet and compressed recordings, but record processing conditions. Distortion, a microphone difference or background noise can affect what reviewers hear; avoid attributing every timbre change to the actor.

## Keep numerical pace measurements transparent

If the production team needs a rate, compute it from an approved transcript and a defined interval. State whether pauses are included. As a hypothetical example, 120 words over a 60-second passage equals 120 words per minute including pauses; this is arithmetic, not a measured model result.

Do not publish a precise rate, pause duration or stress location merely because a generated description supplies one. Verify those values against the recording with an appropriate timing or alignment method. Keep subjective notes separate from measurements.

## Turn a description into a useful production note

Store the take identifier, excerpt location, model draft and director-approved note. Ask whether the note helps distinguish takes or request a specific pickup. Track unsupported adjectives, missed delivery changes and editing time rather than rewarding longer descriptions.

Choose MOSS-Audio if its descriptions help directors review performances accurately and efficiently on the studio’s material. For generating new acted lines instead of describing recordings, the [game character and narration guide](/game-character-lines-neutral-narration/) covers the separate synthesis decision.
