Voice

There are three ways to use your voice:

• Talk (the headphones button, or ⌘⇧V) starts a spoken conversation. Speak naturally; it answers out loud, usually within a second. Interrupt it any time by speaking, or press Space. Click End when you’re done. The conversation is saved as a chat.
• Dictate with the microphone button: your words appear in the message box as you speak, so you can check them before sending. You can also hold the Right Option key anywhere in the app.
• Voice messages (the waveform button) are recorded and sent as audio, so the assistant hears how you said it, not just the words.

Change the voice, speaking speed and sensitivity in Settings → Voice.

If it interrupts itself, the microphone is probably hearing the speakers. Use headphones or lower the volume.
