Talk Mode

1. Listen for speech
2. Send transcript to the model (main session, chat.send)
3. Wait for the response
4. Speak it via ElevenLabs (streaming playback)

​

Behavior (macOS)

• Always-on overlay while Talk mode is enabled.
• Listening → Thinking → Speaking phase transitions.
• On a short pause (silence window), the current transcript is sent.
• Replies are written to the active browser Chat session (same as typing).
• Interrupt on speech (default on): if the user starts talking while the assistant is speaking, playback stops and the next prompt includes the interruption timestamp.

​

Voice directives in replies

{ "voice": "<voice-id>", "once": true }

• First non-empty line only.
• Unknown keys are ignored.
• once: true applies to the current reply only.
• Without once, the voice becomes the new default for Talk mode.
• The JSON line is stripped before TTS playback.

• voice / voice_id / voiceId
• model / model_id / modelId
• speed, rate (WPM), stability, similarity, style, speakerBoost
• seed, normalize, lang, output_format, latency_tier
• once

Config (~/.fased/fased.json)

{
  talk: {
    voiceId: "elevenlabs_voice_id",
    modelId: "eleven_v3",
    outputFormat: "mp3_44100_128",
    apiKey: "elevenlabs_api_key",
    interruptOnSpeech: true,
  },
}

• interruptOnSpeech: true
• voiceId: falls back to ELEVENLABS_VOICE_ID / SAG_VOICE_ID, or the first ElevenLabs voice when an API key is available
• modelId: defaults to eleven_v3 when unset
• apiKey: falls back to ELEVENLABS_API_KEY, or gateway shell profile if available
• outputFormat: defaults to pcm_44100 on macOS/iOS and pcm_24000 on Android. Set mp3_* to force MP3 streaming.

​

macOS UI

• Menu bar toggle: Talk
• Native app settings own local microphone/speech permission prompts.
• Raw talk settings live under Advanced > Config until a focused friendly Talk settings page is available.
• Overlay:
  • Listening: cloud pulses with mic level
  • Thinking: sinking animation
  • Speaking: radiating rings
  • Click cloud: stop speaking
  • Click X: exit Talk mode

​

Notes

• Requires Speech + Microphone permissions.
• Uses chat.send against session key main.
• TTS uses ElevenLabs streaming API with ELEVENLABS_API_KEY and incremental playback on macOS/iOS/Android for lower latency.
• stability for eleven_v3 is validated to 0.0, 0.5, or 1.0; other models accept 0..1.
• latency_tier is validated to 0..4 when set.
• Android supports pcm_16000, pcm_22050, pcm_24000, and pcm_44100 output formats for low-latency AudioTrack streaming.
