Frequently Asked Questions

Which file formats are supported?

You can import audio and video files in the following formats:

m4a mp4 mp3 wav

Which languages can be recognized?

SpeakText supports 35 recognition languages, including Chinese, English, Spanish, French, German, Portuguese, Russian, Japanese, Korean, Arabic and more.

Chinese and 24 European languages: recognition models are built into the app — no download needed.
Japanese, Korean, Arabic and several Asian languages: an offline model (about 150–200 MB) is downloaded once, the first time you select the language. After that, transcription works offline.

Does recognition require an internet connection?

No. Recognition runs entirely on your device. Your audio files and transcription results never leave your device. An internet connection is only used for account sign-in, subscription verification, and the one-time model download mentioned above.

How does the free trial and subscription work?

New users get a 3-day free trial. After the trial, a monthly subscription unlocks unlimited recognition. Payment is charged to the app store account used for the purchase, and the subscription auto-renews unless cancelled at least 24 hours before the end of the current period.

To manage or cancel your subscription:

Open the app store you used to subscribe
Go to your account and open Subscriptions
Select SpeakText to change or cancel the plan

How do I export my results?

Transcripts can be exported as TXT or SRT subtitles via the system share sheet. When exporting SRT, you can optionally control the maximum number of characters per line.

How long are my recognition records kept?

Records are stored locally on your device, and the most recent 100 records are kept automatically — older ones are removed as new ones arrive. You can play, edit, export or delete any record at any time from the History page.

How do I delete my account and data?

Recognition records and imported files are stored only on your device: deleting a record from the History page removes it, and uninstalling the app removes all local data. Because we do not operate a user database of your audio or transcripts, there is no server-side data to delete. If you signed in with Apple and want to revoke access, go to your device Settings → your name → Sign-In & Security → Sign in with Apple; if you signed in with Google, manage the access in your Google account security settings. For anything else, contact us at private@zihiai.com.
