Voice
Voice in Cobalt is three separate things, each independently available:The widget experience
In the web widget, dictation and voice mode sit in the composer, and each answer offers read-aloud. Read-aloud uses the channel’s preferred voice, which you pick in the channel’s branding settings. Voice mode needs microphone permission from the browser — on embedded intranets (SharePoint), the page must allow microphone access; see the SharePoint guide’s troubleshooting if the mic prompt never appears.Slack voice messages
Slack’s own voice clips are supported on the Slack channel: when transcription is enabled in the channel settings, an employee can send a voice message and the agent answers it as a normal text turn. Long clips over the size cap are declined with a short explanation rather than silently dropped.Anonymous visitors and abuse control
On anonymous widget channels (no sign-in), voice is rate-limited so a public embed can’t be abused:- Per-visitor limits on dictation, uploads, and voice-mode sessions.
- A per-tenant daily cap on anonymous voice-mode usage — when the day’s cap is reached, voice mode pauses until the next day while text chat continues normally.
