Generate Subtitles from Any Audio: About Audio to SRT

SRT (SubRip Subtitle) is the most widely used subtitle format. Our audio to SRT converter generates standard-compliant SRT files with timestamps accurate to the millisecond. Each subtitle segment is timed to match the spoken words precisely, so your captions stay in sync with the audio. You can also export as VTT (Web Video Text Tracks) for web-based video players.
Creating subtitles manually takes 5-10 hours per hour of audio. With Vatis, you get a complete SRT file in about 1 minute per hour of audio. Review the subtitles in our editor, adjust timing if needed, and export. It's the fastest way to make your audio and video content accessible.

Can the converter identify different speakers in my Audio file?

Chevron down icon

Yes. Vatis Tech includes automatic speaker diarization — it identifies different voices and labels them throughout the transcript. In the PDF, each speaker's segments are clearly marked. You can rename speakers (e.g., "Speaker 1" → "Maria") in the editor before exporting.

What subtitle formats can I export?

Chevron down icon

SRT and VTT. SRT works with YouTube, VLC, Premiere Pro, Final Cut Pro, and most video platforms. VTT works with HTML5 web video players. Both include millisecond-accurate timestamps.

What's the difference between SRT and VTT?

Chevron down icon

SRT (SubRip) and VTT (WebVTT) are both subtitle formats with timestamps. SRT is the most universal — it works with YouTube, VLC, Premiere Pro, and most platforms. VTT is designed for web browsers and HTML5 video players. Vatis Tech exports both formats. Use SRT unless your platform specifically requires VTT.

Does Vatis Tech provide timestamps for my transcript?

Chevron down icon

Yes. Every segment in the PDF, DOCX, TXT, SRT transcript includes the timestamp from the original video, so you can easily cross-reference the written text with the video recording.

Can I convert MP3 to SRT?

Chevron down icon

Yes. Upload your MP3 file and our AI generates a timed SRT subtitle file automatically. Each spoken segment gets accurate timestamps. This is the fastest way to create subtitles from an audio recording.

Is Vatis Tech the most accurate speech to text app?

Chevron down icon

Vatis Tech achieves 98%+ accuracy on clear audio recordings. For audio with background noise, multiple speakers, or heavy accents, accuracy is typically 96%+. You can improve results further with custom vocabulary for domain-specific terms. Our AI outperforms most competitors on real-world audio because our models are specifically trained on challenging, noisy recordings. For further proof, here's a whitepaper comparing our accuracy with Google, Microsoft and other models.

Can I convert multiple MP3 files at once?

Chevron down icon

Yes. With a paid plan, you can upload multiple MP3 files for batch transcription. Our infrastructure processes them in parallel so you get all your transcripts back quickly. For high-volume needs, our API lets you automate MP3 to text conversion at scale.

Can I edit the subtitles before exporting?

Chevron down icon

Yes. After our AI generates the SRT file, you can review and edit every subtitle segment in our built-in editor. Adjust the text, fix any words, and modify timing — then export the corrected SRT file.

Can I transcribe iPhone Voice Memos?

Chevron down icon

Yes. iPhone Voice Memos are saved as M4A files. Just upload the M4A file to Vatis Tech and get a full transcript in minutes. You can access Voice Memos via iCloud Drive, AirDrop to your computer, or share the file directly from the Voice Memos app.

Do I need to convert M4A to MP3 first?

Chevron down icon

No. Our converter handles M4A files natively. No format conversion needed, just upload the M4A file directly and get your transcript. Converting to MP3 would actually reduce quality and could lower transcription accuracy.

Can I convert WhatsApp voice messages to text?

Chevron down icon

Yes. Export the voice message from WhatsApp (long-press the message, tap Share, then Save to Files or send to your computer). Upload the audio file to Vatis Tech and get a transcript in seconds. WhatsApp voice messages are saved as OGG files, which our converter handles natively.

Can I convert a phone call recording to PDF?

Chevron down icon

Yes. Our converter supports all phone recording formats: M4A (iPhone Voice Memos), OGG (Android), MP3, AAC, and WAV. Just upload the file from your phone or cloud storage (iCloud, Google Drive) and get a transcript. If you've recorded a phone call (using your phone's built-in recorder or an app), export the audio file and upload it to Vatis Tech. The AI transcribes both sides of the conversation with speaker identification, so the PDF shows which participant said what.

Can I add subtitles in multiple languages? What languages are supported?

Chevron down icon

Yes. After generating the initial subtitles, use our translation feature to translate them into 50+ languages with one click. Export each language as a separate SRT file and upload them as alternative subtitle tracks to your video platform. 50+ languages, including English, Spanish, French, German, Italian, Portuguese, Arabic, Japanese, Korean, Mandarin, Hindi, Indonesian, Thai, Russian, and many more.
