How it works, requirements, and troubleshooting transcription issues on iOS. In order to create great AI-enhanced notes, Granola transcribes the audio from your meetings when you choose to. ## How Granola captures transcription Granola records from your iPhone's active microphone input (note that this could be the built-in mic, or could be a bluetooth device if you've got one connected). Granola can pick up on in-person conversations, or sound playing from other devices. Granola temporarily caches audio during the meeting - when transcription is completed, cached audio is deleted from all Granola and third-party systems. ## When does transcription begin? Transcription begins when: * Starting a new note * Tapping 'start notes' for a meeting in progress from the list of upcoming meetings * Tapping 'take notes' from a live activity prompt * Tapping 'start' after opening an upcoming meeting image.png Granola does not auto-transcribe any meetings or conversations without you manually clicking to start taking notes. If you start a note accidentally, click the X on the note in progress card to delete it. ## Transcription indicators You can tell when Granola is transcribing in several ways: * On a note in progress: dancing bars respond to mic input, and the duration timer is active * On lock screen: live activity notification says 'taking notes' with the current duration * In dynamic island: Granola icon visible with duration timer active image.png ## When does transcription end? Transcription ends when you: * Click 'end' on the note card * Click 'end' on the live activity notification Once transcription ends, the app will automatically generate your enhanced notes. It takes a bit longer than on desktop, so Granola will send you a notification when they're ready. If your transcription is taking longer than a few minutes, please open the settings menu from your profile picture on the top-right, and tap report a bug, and include logs. This will generate an email to send to our support team - please let us know a bit of detail about what's happened, including the date/time of your meeting and the title (if it has one). ## Pausing and resuming transcription You can pause and resume transcription from the note in progress card. Your meeting notes won't be generated until you click end to finalize the transcription. ## Speaker identification The transcript will identify speakers as Speaker A, Speaker B, and so on, which should more accurately assign follow-up actions in enhanced notes. We have found that in cases where the speaker identification may not be 100% accurate, the enhanced notes usually do a good job of understanding the nuances of the conversation. ## Viewing the transcript from a completed note To view the full transcript after your meeting, open the note, tap the three-dot menu (**...**) in the top-right corner, and select **View transcript**. From the transcript view, you can also share the transcript. ## Common transcription issues Several issues can impact the quality of Granola's transcription on iPhone: * **Bluetooth or external audio devices**: If a Bluetooth device is connected to your iPhone, Granola may use it as the microphone source instead of the phone's built-in microphone. If the Bluetooth device isn't positioned to pick up the conversation, transcription may capture little or no audio. To use the built-in microphone, disconnect any Bluetooth speakers, headphones, or microphone devices before starting a note. * **Linguistic accuracy**: When meetings are conducted in multiple languages or accents not supported by the current version of Granola, transcription may not accurately capture the dialogue * **Background noise**: While background noise can affect transcription quality, the summary feature does a good job of picking out important points from the conversation * **Length**: Granola for iOS cannot process transcripts that are very long, and roughly 10 hours is the limit for the recording time.
