The company doesn\u2019t publish the exact brand of voice engine in its documentation or on its website.\n\nHere\u2019s what is confirmed about the speech functionality of the BlindShell Classic 3:\n\n---\n\nConfirmed Features of Speech in BlindShell Classic 3:\n\n- The phone is \u201cfully vocalized,\u201d meaning nearly every part of the interface speaks aloud: actions, menus, notifications, alerts. ([blindshell.com](https://www.blindshell.com/us?utm_source=openai))  \n- There is a built-in voice assistant named \u201cLuna,\u201d which responds to spoken commands. ([blindshell.com](https://www.blindshell.com/us/luna?utm_source=openai))  \n- It supports voice dictation (speech-to-text): you can invoke it in writing messages or entering other text. ([teltex.com](https://teltex.com/content/userguides/BlindShell-Classic-3-User-Guide.pdf?utm_source=openai))  \n- Dictation can be either \u201coffline\u201d or \u201conline,\u201d depending on the language and settings. Genres like English, German, Spanish, French, Italian, Dutch, Portuguese, and Russian are explicitly supported offline. ([blindshell.com](https://www.blindshell.com/manual/download.php?file=manual_mandala_en.pdf&utm_source=openai))  \n\n---\n\nWhat isn\u2019t Confirmed:\n\n- The underlying TTS engine or library (e.g. whether it uses Android\u2019s built-in TTS, a third-party, proprietary, or open-source engine).  \n- The specific engine used for offline speech recognition / dictation for supported languages.  \n- Whether the speech voice is synthesized natively on the device or streamed from a server (for \u201conline\u201d) when available.\n\n---\n\nIf you want, I could try to see if the company responded in forums or developer sources with more detail on which engine they use. Would you prefer I dig for that?"
