"The best overall in-domain performance is achieved by Vatis on Antena1 (4.4%), indicating the advantage of proprietary data and domain tuning."
Audio recordings are essential for capturing conversations, but they're terrible for retrieval. Finding a specific quote in a 90-minute recording means scrubbing through the entire file. Sharing an audio file with a colleague means asking them to listen to the whole thing. Quoting from an audio recording in a report or paper means manual transcription — typically 4 to 6 hours of work per hour of audio.
An audio to PDF converter eliminates all of this. Upload your recording, and the AI produces a formatted PDF transcript you can search, share, quote from, and archive. The PDF is a fraction of the file size of the original audio and infinitely more useful for reference.
Interviews - An audio to PDF converter turns a 45-minute interview into a 5-page document you can highlight, annotate, and reference in your work. Timestamps let you go back to the exact moment in the recording when you need the speaker's tone or emphasis.
Meetings - Convert Zoom, Google Meet, and Teams recordings into PDF meeting minutes. The AI identifies each participant and labels their contributions. Share the PDF with attendees instead of circulating a raw audio file. Search across months of meeting PDFs to find when a specific decision was made.
Lectures and seminars - Read the transcript alongside slides, highlight key concepts, and use keyword search to find specific topics across an entire semester of recordings.
Legal and compliance - Law firms convert recorded depositions, client calls, and hearings to PDF for case files. Medical professionals convert patient consultations to PDF for records. Insurance companies convert claim calls to PDF for documentation. In all these cases, a timestamped, speaker-labeled PDF transcript is the standard format for written records.
Podcasts and voice notes - Podcasters convert episodes to PDF for show notes and blog posts. Professionals who dictate ideas via voice memo convert them to PDF for clean documentation. Anyone who captures thoughts by speaking rather than typing can use audio to PDF to create organized written records.

The transcript is generated
Our AI transcription engine converts every spoken word to text with over 98% accuracy. Processing speed: approximately 1 minute per hour of audio-video. The engine automatically detects the language, identifies individual speakers (speaker diarization), and adds precise timestamps to every segment. 98+ languages are supported.
Edit, Export, Share
Review your transcript in our built-in editor. Export as TXT, DOCX, PDF, SRT, or VTT or copy directly to Google Docs. The document includes the full text organized by speaker, with timestamps for each segment. Before exporting, use our built-in editor to review the transcript, correct any words, rename speakers (e.g., "Speaker 1" → "Dr. Martinez"), and adjust formatting.

Our audio to text converter supports 30+ formats including MP3, WAV, M4A, FLAC, AAC, OGG, AIFF, WMA, and OPUS. Files can be up to 5GB and 10 hours long. If you have an unusual format, try uploading it — there's a good chance we support it.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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. The AI automatically detects the language spoken in the video. You can also translate the transcript to 50+ languages before exporting.
Yes. Videos up to 10 hours long and 5GB in size can be converted. The resulting PDF will contain the full transcript with timestamps throughout, making it easy to find specific moments in long recordings.
