Offline speech to text on Android: a practical workflow

Offline speech to text is useful when a connection is unreliable or you want a workflow that does not depend on sending recordings to a cloud transcription service. Scribe is Cadava Team’s Android app for recording and transcribing audio offline. Its Google Play listing advertises 99 languages and SRT export.

An offline workflow still needs preparation. Do not wait until an important recording to discover that a language resource, permission, or device requirement is missing.

Set up before you go offline

Install the app from its official Google Play listing. Review the current requirements and app privacy information there. Complete any initial setup and download any language or model resources requested by the app while you have a connection.

Then test a short recording with networking turned off. Make sure the workflow you intend to use actually works on your phone in that state. Offline transcription is a feature of the relevant processing workflow; it is not a statement that every part of an app, such as installation or optional services, never uses the internet.

Start with clear audio

Place the microphone close enough to capture the main speaker and avoid covering it. Reduce nearby music, fans, and other noise where possible. A quiet ten-second test can reveal microphone or volume problems before a longer session.

Choose the language that matches the speech and speak naturally. Multiple people talking at once, unfamiliar names, and technical terms make review more important. Transcription quality depends on the recording, language, model, and device; there is no universal accuracy percentage to assume.

Only record conversations you have permission to record, and handle the recordings according to your situation and the people involved.

Review the transcript in passes

First, check whether sections are missing or assigned to the wrong words. Then compare names, numbers, dates, and specialized terms with the recording. Those details can look plausible while being incorrect. Finish by adding punctuation and paragraph breaks that make the text easy to read.

If the transcript will be used for decisions or shared as a record, review it against the original audio. Generated text is a draft, not proof that every word was captured correctly. Keep the original recording until you are satisfied with the result.

Choose text or subtitles for the next step

Plain text is convenient for notes and later editing. SRT adds timed cues for a subtitle workflow. After exporting SRT, you can use the browser subtitle editor to edit text or apply a constant timing shift. Read the SRT timing guide if subtitles are consistently early or late.

The website tools and the Android app are separate products. This website does not currently transcribe uploaded audio; use the app’s supported recording and transcription workflow.
