Can Apple Intelligence transcribe voice memos?
You can transcribe voice memos and any audio file on your iPhone, iPad, or Mac entirely on-device. In Lyonesse, the transcription runs on Apple's built-in speech engine or NVIDIA Parakeet, and Apple Intelligence then summarizes the result and answers questions about it. No audio is uploaded, and the whole thing works in airplane mode.
How the on-device pipeline fits together
It helps to separate two jobs. Transcription turns audio into text, and that runs on Apple's speech engine or the NVIDIA Parakeet model on your device. Intelligence is the layer that summarizes, drafts, and answers questions, and that runs on Apple Intelligence or the downloadable Qwen 3 model. Leave Lyonesse on Auto and it picks the best available for your hardware.
Both layers stay local. There is no cloud AI or transcription provider in the path, so a private voice memo stays a private voice memo.
Why transcribe voice memos on-device?
Voice memos are often the unguarded stuff: a quick thought, an interview, a doctor reading notes between patients, a journalist capturing a source. Sending that audio to a transcription service creates a copy you do not control. On-device transcription gives you the text without the upload, and it keeps working when you have no signal, which is exactly when you tend to be recording in the field.
What you get after transcription
Once the audio is text, Apple Intelligence can summarize it in the style you want: concise, bullets, structured, detailed, action items, or an outline. Ask Lyonesse lets you ask follow-up questions about the recording, like "what did she say the deadline was," with answers that cite the transcript. You can export the result to PDF or text with the summary and full transcript attached, and send any action items to Apple Reminders.

Which model is best for accuracy?
Leave it on Auto: Lyonesse picks Apple's engine where it supports your language and NVIDIA Parakeet otherwise. In our published English benchmark, both beat every Whisper model we previously shipped. If you want speed and lower battery use, Apple's built-in engine is quick. Either way the audio is processed locally, so picking a more accurate model does not mean sending your recording anywhere.
Works on iPhone, iPad, and Mac
The same on-device flow runs across Apple devices, in 15 languages, with multilingual AI summaries. You can record directly in Lyonesse or import an existing voice memo or audio file. Optional iCloud sync is off by default, so your recordings stay on the device you made them on unless you decide otherwise.
