Turn a Zalo Voice Message into a Transcript
Zalo has no way to connect to your conversations and pull a voice message automatically: there is no Zalo integration. To get a transcript, you first need the audio as a file, either saved from the chat or recorded while it plays.
Reading the text back is faster than replaying a voice message to catch one detail, and it gives you a written record of what was said.
What you get:
- speaker identification, useful for group chats and messages with more than one speaker
- Timestamps on every segment, for pointing to a specific moment
- Export as PDF, DOCX, TXT, SRT and VTT
- transcript and caption translation, so a voice message in another language reads in yours
- AI chat with the transcript, so you can ask a question about it instead of replaying the whole message
- Free plan: 2 transcriptions of recordings up to 45 minutes each
How to Transcribe a Zalo Voice Message
- Get the audio off Zalo: Open the conversation, long-press the voice message, and use Zalo’s forward or save option to get the file onto your device. If there is no save option for that message, play it on speaker and record it instead, using the ScreenApp mobile app or your browser’s microphone recorder.
- Upload the file: ScreenApp accepts MP3, M4A, MP4A, M4B, AAC, WAV, OGG, OPUS, FLAC, AIFF, WMA, WEBMA, MKA, AC3, EAC3, WV, AMR, DSF, DFF for uploads, so most saved Zalo voice messages work without converting anything first.
- Read the transcript: The transcript, with speaker labels and timestamps, is ready a few minutes later. Export it as PDF, DOCX, TXT, SRT and VTT, or ask the AI a question about the content.
Accuracy depends on the recording, not just the transcription engine, and it also depends on the language. Vietnamese is one of the languages where accuracy is currently lower than average. A voice message saved directly from Zalo transcribes more cleanly than one re-recorded off a speaker in a noisy room. See how we measure accuracy.

People saving a conversation turn a voice message into text so they have a written copy that does not depend on the Zalo app or account staying around.
Multilingual communicators transcribe a voice message in one language and translate it, so participants who speak different languages can read the same conversation.
