From Spanish and French to Japanese and Arabic, Sonix supports translation between all major world languages.
Audio translation is a two-step process that converts spoken content from one language into written text in another language. First, advanced speech recognition technology transcribes the audio into text in the original language. Then, neural machine translation converts that text into your target language while preserving meaning, context, and tone.
Modern AI models have revolutionized this process. They can handle diverse accents, dialects, and speaking styles with remarkable accuracy. Sonix supports 53+ languages including Spanish, French, German, Japanese, Mandarin Chinese, Arabic, Portuguese, and many more. Whether you have a podcast, interview, meeting recording, or video content, the translation process works the same way.
Translating audio and video content opens your work to global audiences without the expense of re-recording in multiple languages. A single podcast episode can reach listeners in dozens of countries. A training video can educate teams across international offices. A documentary can connect with viewers worldwide.
There are practical benefits too. Many industries require multilingual accessibility for compliance. Translated transcripts improve SEO by helping search engines index your content in multiple languages. And content repurposing becomes straightforward: one recording becomes a library of international assets. For businesses expanding globally, audio translation eliminates the need for separate production teams in each market.
The quality of your translation depends heavily on your source material. Start with clear, high-quality audio where speakers enunciate and minimize background noise. Multiple overlapping speakers or heavy accents can reduce accuracy, though modern AI handles these challenges better than ever.
Before translating, review and polish your transcript in the original language. Fix any transcription errors, remove filler words, and ensure the text reads naturally. The cleaner your source transcript, the better your translation will be. When reviewing translations, consider cultural context: idioms and expressions may need adjustment to resonate with your target audience. Sonix provides a side-by-side editor so you can compare the original and translated versions easily.
Media companies use audio translation to localize documentaries, films, and news content for international distribution. The process of creating multilingual subtitles or dubbed versions starts with an accurate translated transcript.
Researchers and academics translate interview recordings to analyze multilingual data sets or collaborate across language barriers. Global businesses create training materials, compliance documentation, and internal communications in multiple languages from a single source recording. Educational institutions build multilingual course content to serve diverse student populations. Podcasters expand their reach by publishing transcripts in multiple languages, making their content accessible to non-native speakers. Legal and government organizations translate depositions, hearings, and official proceedings for international cases.
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.
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.
Translation accuracy depends primarily on your source audio quality. Clear audio with single speakers typically achieves 95%+ accuracy in both transcription and translation. We always recommend reviewing the transcript before translation and checking the final translated text before publishing.
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.
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.
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.
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.
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.
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. Upload Spanish audio and translate directly to Japanese, for example.
Yes. Sonix integrates with Zapier for workflow automation, plus direct connections to Dropbox, Google Drive, and Box for file storage. We also offer a full API for developers who want to build custom integrations. Exported transcripts work with any document or subtitle editing software.
