From 8038fed16c0cb33e4e905897c324feafe00f55de Mon Sep 17 00:00:00 2001 From: Kelvin Amoaba <97001695+AmoabaKelvin@users.noreply.github.com> Date: Sat, 7 Nov 2026 02:11:20 +0000 Subject: [PATCH] feat(dictation): stop desktop dictation after a minute of silence (#39131) * feat(dictation): stop desktop dictation after a minute of silence A toggle dictation left running keeps the mic open indefinitely. Stop it a minute after the last speech, with a toast, like the phone's tap mode. A held push-to-talk key is never stopped; its release ends the session. Mobile's timer moves into src/shared so both apps use the same rule, and the shared meter now records when it last heard speech. * fix(dictation): gate the silence stop on hold mode, as the phone does * refactor(dictation): let the desktop silence hook own the hold-mode rule, as mobile's does * refactor(dictation): move the capture meter into its own hook * refactor(dictation): initialise the capture meter ref without a render write --- .../use-mobile-dictation-silence-stop.ts | 18 +------ .../dictation/DictationController.tsx | 11 ++++- .../dictation/use-dictation-silence-stop.ts | 34 +++++++++++++ .../src/hooks/use-audio-capture-meter.ts | 49 +++++++++++++++++++ src/renderer/src/hooks/use-audio-capture.ts | 45 ++--------------- src/renderer/src/i18n/locales/de.json | 3 +- src/renderer/src/i18n/locales/en.json | 3 +- src/renderer/src/i18n/locales/es.json | 3 +- src/renderer/src/i18n/locales/fr.json | 3 +- src/renderer/src/i18n/locales/ja.json | 3 +- src/renderer/src/i18n/locales/ko.json | 3 +- src/renderer/src/i18n/locales/pt.json | 3 +- src/renderer/src/i18n/locales/ru.json | 3 +- src/renderer/src/i18n/locales/tr.json | 3 +- src/renderer/src/i18n/locales/zh-Hant.json | 3 +- src/renderer/src/i18n/locales/zh.json | 3 +- src/shared/dictation-audio-meter.ts | 11 +++-- src/shared/dictation-silence-stop.ts | 24 +++++++++ 18 files changed, 154 insertions(+), 71 deletions(-) create mode 100644 src/renderer/src/components/dictation/use-dictation-silence-stop.ts create mode 100644 src/renderer/src/hooks/use-audio-capture-meter.ts create mode 100644 src/shared/dictation-silence-stop.ts diff --git a/mobile/src/session/use-mobile-dictation-silence-stop.ts b/mobile/src/session/use-mobile-dictation-silence-stop.ts index 7dcf2afa96a..11cc537bccc 100644 --- a/mobile/src/session/use-mobile-dictation-silence-stop.ts +++ b/mobile/src/session/use-mobile-dictation-silence-stop.ts @@ -1,9 +1,8 @@ import { useEffect, useEffectEvent } from 'react' +import { watchDictationSilence } from '../../../src/shared/dictation-silence-stop' import type { UseMobileDictationResult } from '../hooks/mobile-dictation-session-state' import { nativeChatDictationCopy } from './mobile-session-native-chat-dictation-copy' -const DICTATION_SILENCE_STOP_MS = 60_000 -
