| description | Text-to-speech and speech-to-text via Together AI, including REST, streaming, and realtime WebSocket TTS, plus transcription, translation, diarization, timestamps, and live STT. Reach for it whenever the user needs audio in or audio out on Together AI rather than chat generation, image or video creation, or model training. |
Together Audio
Overview
Use Together AI audio APIs for:
- text-to-speech generation
- streaming or realtime voice output
- speech-to-text transcription
- translation, diarization, and timestamps
- live captioning and realtime transcription
When This Skill Wins
- Generate spoken audio from text
- Transcribe uploaded audio files or URLs
- Add realtime voice or captioning to an app
- Extract speaker segments or word timings
Hand Off To Another Skill
- Use
together-chat-completions for text-only generation
- Use
together-video or together-images for visual generation workflows
- Use
together-dedicated-endpoints only when the audio model itself must be hosted on dedicated infrastructure
Quick Routing
- REST TTS or streaming TTS
- Realtime TTS over WebSocket
- File transcription, translation, diarization, or timestamps
- Realtime STT
Workflow
- Confirm whether the task is TTS or STT.
- Choose REST, streaming, or realtime transport based on latency and interaction needs.
- Pick the model and response format from the relevant reference file.
- Start from the matching script instead of rebuilding the request contract from memory.
- For Python STT uploads, open audio files in binary mode and pass the file handle rather than a bare path string.
High-Signal Rules
- Python scripts require the Together v2 SDK (
together>=2.0.0). If the user is on an older version, they must upgrade first: uv pip install --upgrade "together>=2.0.0".
- Use
client.audio.speech.create() for TTS.
- REST TTS returns a
BinaryAPIResponse; call response.write_to_file(path) to save it. Do NOT use stream_to_file (it does not exist on this object).
- Streaming TTS (
stream=True) returns a Stream of AudioSpeechStreamChunk objects. Iterate chunks, check chunk.type, and decode base64.b64decode(chunk.delta) for audio data. There is no file-writing helper on the stream object.
- Use
client.audio.transcriptions.create() for transcription and client.audio.translations.create() for translation.
- Batch transcription and translation share hard limits: 500 MB direct upload, 1 GB URL-fetch, 4 hours of audio per request. For larger payloads, pass a public HTTPS URL on
file=; for longer audio, split into ≤ 4 h chunks. See the Limits section of references/stt-models.md.
- Realtime APIs require audio-format discipline; confirm PCM expectations before streaming bytes.
- Diarization and word timestamps change response shape; code for the richer verbose output explicitly.
