Telegram Voice To Voice Macos

Telegram voice-to-voice for macOS Apple Silicon: transcribe inbound .ogg voice notes with yap (Speech.framework) and reply with Telegram voice notes via say+ffmpeg. Not compatible with Linux/Windows.

Telegram voice-to-voice (macOS Apple Silicon only)

This is an OpenClaw skill.

Requirements

• macOS on Apple Silicon.
• yap CLI available in PATH (Speech.framework transcription).
  • Project: https://github.com/finnvoor/yap (by finnvoor)
• ffmpeg available in PATH.

Compatibility note (important)

This skill is macOS-only (uses say + Speech.framework). The skill registry cannot enforce OS restrictions, so installing/running it on Linux/Windows will result in runtime failures.

Persistent reply mode (voice vs text)

Store a small per-user preference file in the workspace:

• State file: voice_state/telegram.json
• Key: Telegram sender user id (string)
• Values:
  • "voice" (default): reply with a Telegram voice note
  • "text": reply with a single text message

If the file does not exist or the sender id is missing: assume "voice".

Toggle commands

If an inbound text message is exactly:

• /audio off → set state to "text" and confirm with a short text reply.
• /audio on → set state to "voice" and confirm with a short text reply.

Getting the inbound audio (.ogg)

Telegram voice notes often show up as <media:audio> in message text. OpenClaw saves the attachment to disk (typically .ogg) under:

• ~/.openclaw/media/inbound/

Recommended approach:

1. If the inbound message context includes an attachment path, use it.
2. Otherwise, take the most recent *.ogg from ~/.openclaw/media/inbound/.

Transcription

Default locale: macOS system locale.

Optional env:

• YAP_LOCALE — override the transcription locale (e.g. it-IT, en-US).

Preferred:

• yap transcribe --locale "${YAP_LOCALE:-<system>}" <path.ogg>
  • If YAP_LOCALE is not set, the helper script will use the macOS system locale (from defaults read -g AppleLocale).

If transcription fails or is empty: ask the user to repeat or send text.

Helper script:

• scripts/transcribe_telegram_ogg.sh [path.ogg]

Reply behavior

Mode: voice (default)

Voice default: SYSTEM (uses the current macOS system voice). You can override by passing a specific voice name to the helper script.

1. Generate the reply text.
2. Convert reply text to an OGG/Opus voice note using:

• scripts/tts_telegram_voice.sh "<reply text>" [SYSTEM|VoiceName]

The script prints the generated .ogg path to stdout.

3. Send the .ogg back to Telegram as a voice note (not a generic audio file):

• use the message tool with asVoice: true and media: <path.ogg>
• optionally set replyTo to thread the response

Notes:

• Use SYSTEM to rely on the current macOS system voice (recommended).

Mode: text

Reply with a single text message:

• Transcription: <...>
• Reply: <...>
