Saiyia voice assistant: features and usage guide
Saiyia (赛伊) is an AI voice assistant for web and iPhone. It combines voice and text chat, text-to-speech, live transcription, translation, study, and meeting notes in one account.
Voice chat and five conversation modes
Saiyia accepts typed messages and microphone speech for AI conversations. Choose Daily for questions and writing, Meeting for notes and action items, Translate for bilingual translation, Study for vocabulary, grammar, and role-play, or Companion for conversational support. These modes guide the AI response; generated answers still need review before you rely on them.
After signing in, open Chat, select a mode, and type a message or use the microphone. For meeting notes, provide the discussion text and review names, decisions, and action items against the original discussion.
Open Chat (sign-in required)Text-to-speech with playback and audio download
Text-to-speech (TTS) converts written text into spoken audio. Saiyia plays audio as it is generated, then keeps the completed audio available for replay and download. This is useful for listening to a draft, preparing spoken material, or practicing pronunciation.
Open Voice tools and select the text-to-speech tab. Type or dictate text, choose a voice, and select Synthesize & play. When generation finishes, use the audio controls to replay it or download the audio. Cloud TTS requires Pro access or an active trial.
Open text-to-speech (sign-in required)Live transcription for lectures and interview practice
Live transcription converts microphone speech into text during recording. It is separate from saving an audio recording. Saiyia offers Lecture notes, Interview practice, and Free form modes, with an AI analysis action for the resulting text.
Open Voice tools and select live transcription. Choose a mode, allow microphone access, and start recording. Stop when finished, review the recognized text, and ask AI to organize the notes or review your practice. Recognition needs an internet connection; background noise and microphone placement can affect the result.
Open live transcription (sign-in required)Translation and language study
Translate mode handles bilingual translation and can explain ambiguous wording. Study mode supports vocabulary explanations, grammar correction, and role-play. You can use speech playback to listen to text alongside these conversations.
In Chat, choose Translate or Study and provide the text, target language, and relevant context. For practice, describe a situation and ask for a dialogue. Review translations involving specialist terms or important commitments before using them.
