soniox
The official Python SDK for the Soniox API (STT, REST)
Decision gist · record as of 2026-08-14
Yes. The SDK is actively maintained, has low install friction, no known vulnerabilities, and a permissive license. Install it if you need to integrate Soniox's STT or TTS APIs into a Python application. Avoid Python 3.13.6 specifically due to a documented ssl regression; any other 3.10–3.14 version is safe.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires SONIOX_API_KEY environment variable or explicit API key passed to client.
- Avoid Python 3.13.6 for realtime operations.
- Low friction install with three lightweight runtime dependencies (httpx, pydantic, websockets).

What it is and what it does
Soniox is the official Python SDK for accessing Soniox's speech and audio APIs. It provides both synchronous and asynchronous clients that wrap REST and WebSocket endpoints for speech-to-text transcription, text-to-speech synthesis, voice cloning, and usage/cost reporting. The SDK handles authentication via API key, file uploads, model selection, and typed request/response objects through pydantic.
Typical workflows include transcribing audio files end-to-end in a single call, streaming realtime speech recognition or synthesis over WebSocket, cloning voices from reference audio for custom TTS, and querying daily spend and per-request logs. The package is actively maintained, supports Python 3.10 through 3.14, and has minimal dependencies (httpx, pydantic, websockets).
Use it for
- Transcribe audio files or URLs to text in a single call with automatic cleanup.
- Stream live audio over WebSocket for low-latency speech-to-text in real-time applications.
- Generate speech from text with built-in or cloned voices, optionally streaming audio chunks as they arrive.
- Clone a custom voice from a reference audio clip and reuse it across TTS requests.
- Track API usage and costs per model and per request over a date range.
- Build async applications that handle concurrent STT/TTS operations without blocking.

Before you install
Low friction install with three lightweight runtime dependencies (httpx, pydantic, websockets). Active maintenance—last commit 2026-08-11, released 3 days ago. Supports modern Python versions (3.10–3.14). Note: avoid Python 3.13.6 due to a CPython ssl regression that hangs realtime STT/TTS.
