Voice & TTS

Pawz supports text-to-speech so agents can speak their responses aloud.

​

Setup

Go to Settings → Voice to configure TTS.

​

Providers

​

Google Cloud TTS

No API key needed — uses the free web endpoint. Chirp 3 HD voices: Puck, Charon, Kore, Fenrir, Leda, Orus, Zephyr, Aoede, Callirhoe, Autonoe Neural2 voices: en-US-Neural2-A through F Journey voices: en-US-Journey-D, en-US-Journey-F, en-US-Journey-O

​

​

ElevenLabs

Requires an ELEVENLABS_API_KEY. Voices: Sarah, Charlie, George, Callum, Liam, Charlotte, Alice, Matilda, Will, Jessica, Eric, Chris, Brian, Daniel, Lily, Bill Models: Extra settings:

• Stability (0–1, default 0.5) — higher = more consistent
• Similarity boost (0–1, default 0.75) — higher = closer to reference voice

​

Settings

​

Speech-to-text (STT)

Pawz uses OpenAI Whisper for speech-to-text transcription: STT is used in Talk Mode and any voice input feature. Audio is captured as WebM/Opus (or OGG fallback), base64-encoded, and sent to the Whisper endpoint for transcription.

​

Audio capture settings

The microphone input uses these Web Audio constraints:

​

Voice activity detection (VAD)

Talk Mode includes built-in voice activity detection to avoid sending silence to the transcription API: :::info VAD works by checking the size of each recording chunk. Very short or silent recordings produce small files that are automatically discarded before being sent to Whisper. :::

​

Talk mode

Click the microphone icon in the chat header to enter talk mode. Your speech is transcribed and sent to the agent, and the response is spoken back. Requires either:

• Whisper API skill (OpenAI API key)
• Whisper Local skill (install whisper binary)

​

How talk mode works

1. Listen — microphone captures audio in 8-second windows
2. Transcribe — audio is sent to Whisper STT → text
3. Process — transcribed text is sent to your agent as a chat message
4. Speak — agent’s response is synthesized via your configured TTS provider
5. Repeat — next recording cycle starts after playback finishes

​

Voice command mode vs dictation mode

In voice command mode, every 8-second recording window is independently transcribed and sent to the agent. The agent responds and the reply is spoken aloud before the next cycle begins. To use dictation mode, start your utterance with “dictate” or “type” — the agent will accumulate your speech into a document rather than responding conversationally.
