Using Voice Input for mobile
The Voice Input feature allows users to easily transcribe spoken words into written text. Voice-to-text can be accessed directly from the search bar or Otto chat.
To begin, tap the microphone button 
in your Otto chat search bar to start the transcription. To show that Otto is listening, the listening icon 
will display while you're speaking. Once your message has been transcribed, it will appear as text in your search bar.
