Walkie-Talkie Mode

This skill automates the voice-to-voice loop on WhatsApp using local transcription and local TTS.

Workflow

Incoming Audio: When a user sends an audio/ogg/opus file:

- Use tools/transcribe_voice.sh to get the text.
- Process the text as a normal user prompt.

Outgoing Response:

- Instead of a text reply, generate speech using bin/sherpa-onnx-tts.
- Send the resulting .ogg file back to the user as a voice note.

Triggers

• User sends an audio message.
• User says "activa modo walkie-talkie" or "hablemos por voz".

Constraints

• Use local tools only (ffmpeg, whisper-cpp, sherpa-onnx-tts).
• Maintain a fast response time (RTF < 0.5).
• Always reply with BOTH text (for clarity) and audio.

Manual Execution (Internal)

To respond with voice manually:

bin/sherpa-onnx-tts /tmp/reply.ogg "Tu mensaje aquí"

Then send /tmp/reply.ogg via message tool with filePath.
