How this service works
Automated quality assurance for Text-to-Speech audio. Submit a batch of Text-to-Speech files and get a per-file anomaly report - voice drift, glitches, accent shifts - so you regenerate only the bad ones.
Output
A JSON object containing an overall audit score, per-check sub-scores (quality, comparison, pacing, script accuracy), a list of specific files flagged for regeneration with the reasons why, a report URL for the dashboard, the number of credits used, and total processing time. For example: 3 of 5 files flagged, with track_03.wav identified as having high artifact count.
Example use cases
Example prompt
“Can you audit these 5 TTS audio files for quality issues — run quality analysis, pacing, and cross-file comparison at high accuracy, and label the batch 'product-launch-v2' so I can find it in the dashboard later?”
Technical details
Endpoint
GEThttps://api.ttsaudit.com/v1/auditWhen to prefer
Choose this endpoint when you have a batch of AI-generated TTS audio files that need quality gating before publication — especially when you want to identify only the bad files for regeneration rather than re-rendering everything. It is ideal for production pipelines producing large volumes of TTS content (e.g. audiobooks, voice UI, e-learning) where catching artifacts, pacing errors, voice drift, or script deviations early saves regeneration cost. Prefer this over manual listening or generic audio analysis tools when you need structured, per-file reports with actionable regeneration recommendations.
Side effects
- Unsupported audio format returns an error — ensure files are in a supported binary audio format like WAV or MP3
- Payment not completed via x402 results in a 402 Payment Required response before audit runs
- Invalid or missing audio files array causes a 400 Bad Request
- scriptAccuracy enabled without a reference script may return incomplete results
- Files exceeding size limits may be rejected
- Wallet address mismatch between X-Wallet header and signing wallet may prevent cached pricing
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| pace | string | Run pacing/WPM analysis |
| files | array | Audio files to audit (multipart/form-data) |
| quality | string | Run per-track quality analysis (SNR, clipping, artifacts) |
| X-Wallet | string | Optional header (not a body field). Pass the payer wallet address ahead of the 402 response so previously-audited files return at the cached price (0.2 credits = $0.002 per analysis). Must match the wallet that signs the x402 payment. |
| accuracy | string | Transcription accuracy tier (default: standard) |
| comparison | string | Run cross-file similarity analysis |
| customLabel | string | Optional human-readable label (max 120 chars) shown in the dashboard sidebar to help identify this audit. Useful for batches keyed by your own job IDs. |
| scriptAccuracy | string | Run transcript-vs-script accuracy analysis |
