Nox Voice 1 Advance
Natural spoken answers, with a clear daily Free allowance
Nox Voice 1 Advance is a spoken conversation system that keeps the simplicity of a phone call while preserving a written record in Nox. It captures a spoken turn, transcribes it, produces a concise answer, and speaks that answer aloud before returning to listen.
Voice 1 Advance is built as a complete voice pipeline rather than a read-aloud switch on text chat. Speech is captured in the browser, transcribed for Nox, answered in a concise spoken style, and rendered as natural audio. Every completed exchange is saved into the same chat thread, so the conversation remains available to read afterward.
The system is tuned for short, clear spoken responses. It listens for a completed phrase, begins processing immediately, and starts speaking an answer as soon as a natural sentence is ready. If a reply is already playing, a new spoken question stops that playback and begins the next turn.
Voice 1 Advance currently speaks English. The companion Voice 1.2 mode supports live multilingual conversation for plans that include it; Advance is the streamlined voice option available across the Nox family.
Every Advance call has a firm time boundary. A call can run for up to 15 minutes on paid plans. Free accounts include one session of up to one minute each UTC day, so anyone with a Nox account can try the full voice flow without an upgrade while the service stays predictable and available.
As with text chat, Voice 1 Advance runs behind Leo. Spoken turns are screened with the same deterministic emergency-safety backstop, and urgent guidance takes priority when a voice transcript indicates an emergency.
