A cross-platform mobile app that helps you to generate transcripts either from a voice recording or by uploading an audio file. The project uses a totally serverless architecture.

The mobile app is created using Flutter which is integrated with Firebase. Firebase Cloud Functions is used to deploy the backend code required for communicating with the Deepgram API.

The Flutter application consists of the following pages/screens:

• Login Page
• Register Page
• Dashboard Page
• Record Page
• Upload Page
• Transcription Page

For authenticating the user inside the app -- Login and Register pages are used. Authentication is required to generate unique accounts for users required for storing the generated transcripts to Firestore and facilitate cloud-sync.

The Dashboard Page displays a list of all the transcripts currently present on the user's account. It also has two buttons - one for navigating to the Record Page and the other for navigating to the Upload Page.

Record Page lets you record your audio using the device microphone and the transcribe it using Deepgram. You always have an option to re-record if you think the last recording wasn't good.

From the Upload Page, you can choose any audio file present on your device and generate the transcript of it.

Transcription Page is where the entire transcript can be viewed. It has an audio-transcript synchronized playback that highlights the text transcript part with respect to the audio that is playing.

You can also see the confidence map of each of the parts of the transcript (it shows how much accurate is that part of transcript generation - darker is higher confidence).

You can also easily print or share the generated transcript in the PDF format.
