Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| modelId | string | yes | The id returned by list_voice_models. |
| fileName | string | yes | Original WAV, MP3, FLAC, M4A, or OGG vocal filename. |
| sizeBytes | integer | no | Exact byte size of the source audio. Supply it whenever the client can measure the file so interrupted uploads are verifiable and safely resumable. |
| durationSeconds | number | yes | Measured duration of the source audio in seconds. NiceVois uses this to verify that the account can download the result before cloud work. |
| transpose | integer | no | Pitch shift in semitones, from -24 through 24. Use 0 when no shift was requested. |
