// OVERVIEW

Voice is the difference between asking a question while you're cooking and waiting until you sit back down at a keyboard. J@rv1s wakes in under a second, streams its reply with natural prosody, and lets you barge in mid-sentence to redirect. Push-to-talk or always-listening — your call.

// DIAGRAM, FIG.01
YOU SPEAKJ@RV1S REPLIES~800ms WAKE

From end of your sentence to first audible word: under 800ms on supported devices.

// KEY FEATURES
Natural prosody

Not a robot reading. Pauses, emphasis, and breath where a person would put them.

Streaming

J@rv1s starts speaking the moment it has the first phrase, not after the whole reply is composed.

Barge-in

Interrupt mid-sentence to redirect. The agent stops, listens, and replans.

Quiet mode

Whisper-quality output for headphones in shared spaces.

// HOW IT FLOWS
STEP 01
Wake

Say the wake phrase, or hold the bound key for push-to-talk.

STEP 02
Ask

Talk like you would to a person. No keywords required.

STEP 03
Listen

Streamed reply starts almost immediately.

STEP 04
Steer

Interrupt any time. J@rv1s catches the new direction without losing context.
