Frequently asked questions about Sonix
How do I translate an audio or video file with Sonix?
Upload your file to Sonix and wait for the transcript to complete. Review and polish the transcript if needed, then click the Translation menu and select your target language. Your translated transcript will be ready in moments.
What languages does Sonix support for translation?
Sonix supports 53+ languages for translation including Spanish, French, German, Japanese, Mandarin Chinese, Arabic, Portuguese, Italian, Korean, Dutch, Russian, Hindi, and many more. You can translate between any combination of supported languages, giving you 2809 translation pairs.
How accurate is automated audio translation?
Translation accuracy depends primarily on your source audio quality. Clear audio with single speakers typically achieves 95%+ accuracy in both transcription and translation. Sonix recommends reviewing the transcript before translation and checking the final translated text before publishing.
How long does translation take?
Translation is nearly instant once you have your transcript. The transcription step takes roughly the same duration as your file (a 15-minute recording takes about 15 minutes to transcribe). After that, translation to any language completes in seconds.
What file formats can I translate?
Sonix supports all major audio formats (MP3, WAV, M4A, FLAC, OGG, WMA) and video formats (MP4, MOV, AVI, MKV, WebM). You can also import directly from cloud storage like Dropbox, Google Drive, and Box.
Can I edit the translation before downloading?
Yes. Sonix provides a side-by-side editor that shows your original transcript next to the translated version. You can edit either transcript, and changes remain synced to the original timestamps. This makes it easy to fine-tune translations for accuracy and natural phrasing.
What's the difference between transcription and translation?
Transcription converts speech to text in the same language (English audio to English text). Translation converts text from one language to another (English text to Spanish text). Sonix does both: first transcribing your audio, then translating that transcript to your chosen language.
How much does audio translation cost?
Translation is charged at the same rate as transcription. Premium subscribers pay $5 per hour of audio. Pay-as-you-go users pay $10 per hour. A 30-minute file that you transcribe and translate would be billed as 30 minutes total (not 60), since translation adds no extra charge beyond the transcription rate.
Can I translate directly between two non-English languages?
Yes. You can upload audio in any supported language and translate directly to any other supported language. There's no requirement to use English as an intermediate step. For example, you can upload Spanish audio and translate directly to Japanese.
Does Sonix integrate with other tools?
Yes. Sonix integrates with Zapier for workflow automation, plus direct connections to Dropbox, Google Drive, and Box for file storage. Sonix also offers a full API for developers who want to build custom integrations. Exported transcripts work with any document or subtitle editing software.
