Echo: Semantic Voice Keyboard

Echo turns speech into editable text for messages, email, notes and prompts. See text arrive as you speak, then review and edit it. Quick provides transcription without LLM rewriting; Polish is optional AI editing. A personal dictionary lets you manually save names, project terms and specialist vocabulary. Echo supports Chinese-English mixed-language input, an iPhone keyboard for compatible text fields, and a Mac voice-input workflow. Speech recognition and AI editing use cloud services and need an internet connection. Recognition can make mistakes, so review important text before sending. Free download with paid subscriptions; available features vary by platform and version.
