name: salute-speech description: > Transcribe audio files using Sber Salute Speech async API. Russian-first STT with support for ru-RU, en-US, kk-KZ, ky-KG, uz-UZ. metadata: { "openclaw": { "requires": { "bins": ["uv"], "env": ["SALUTE_AUTH_DATA"] }, "primaryEnv": "SALUTE_AUTH_DATA" } }

Audio Transcription with Sber Salute Speech

Transcribe audio/video files to text with timestamps via Salute Speech async REST API.

Requirements

• API Key: Environment variable SALUTE_AUTH_DATA must be set (Base64-encoded client_id:client_secret or raw authorization key from https://developers.sber.ru/studio/).
• SSL note: The script disables SSL verification by default (verify_ssl=False) because Sber's certificate chain is non-standard. This is expected.

Supported formats & encodings

Audio encoding	Content-Type	Typical extensions
MP3	audio/mpeg	.mp3
PCM_S16LE	audio/wav	.wav
OPUS	audio/ogg	.ogg, .opus
FLAC	audio/flac	.flac
ALAW	audio/alaw	.alaw
MULAW	audio/mulaw	.mulaw

Supported languages

ru-RU, en-US, kk-KZ (Kazakh), ky-KG (Kyrgyz), uz-UZ (Uzbek).

Workflow

1. Identify input files — from user request.
2. Read API key from host environment.
3. Run transcription — execute salute_transcribe.py with uv and appropriate arguments.
4. Deliver results — present to user human-readable transcript with timestamps to the user and give a direct link to files.

Usage

uv run --with requests {baseDir}/salute_transcribe.py \
  --file /path/to/audio.mp3 \
  --output_dir ~/.openclaw/workspace/transcriptions \
  --lang ru-RU

Arguments

Argument	Required	Default	Description
--file	Yes	—	Path to audio/video file
--output_dir	No	~/.openclaw/workspace/transcribations	Output directory for results
--lang	No	ru-RU	Language code: ru-RU, en-US, kk-KZ, ky-KG, uz-UZ
--audio-encoding	No	MP3	Codec: MP3, PCM_S16LE, OPUS, FLAC, ALAW, MULAW
--model	No	general	Recognition model: general or callcenter
--hyp-count	No	1	Number of alternative hypotheses: 1 or 2
--max-wait-time	No	300	Max seconds to wait for async result
--print	No	off	Also print transcription to stdout

Content-Type mapping

When the file extension doesn't match audio/mpeg, adjust content_type in the script or add logic. Current default is audio/mpeg (MP3). For .wav files use audio/wav, etc.

Output files

For input file meetingABC.mp3 the script produces:

File	Description
meetingABC_recognition_orig.json	Raw API response (full JSON with all hypotheses, timing, confidence)
meetingABC_pretty.txt	Formatted human-readable transcript with timestamps

Output text format

[00:01 - 00:20]:
Ну, даже если сосредоточиться на идее узкой щели.

[00:20 - 00:45]:

Notes

• Token is valid for ~30 minutes; the script fetches a new one each run.
• Large files (>1 hour) may need --max-wait-time increased beyond 300s.
• The callcenter model is optimized for telephony audio (8kHz, mono).
• Profanity filter is disabled by default (enable_profanity_filter=False).
• The script uses normalized text by default (numbers as digits, abbreviations expanded). Raw text is also available in the JSON output.
