Frequently Asked Questions

Speech translation converts spoken audio in one language into spoken audio in another language, preserving the original speaker's voice characteristics. It combines speech recognition, text translation, and voice cloning.

We support translation between 50+ languages using our speech-to-text models, and voice preservation in 8+ languages using CosyVoice 2. The most popular pairs are English ↔ Spanish, English ↔ Chinese, and English ↔ French.

Translation accuracy depends on the language pair and audio quality. For major language pairs (English, Spanish, French, German, Chinese), accuracy is comparable to professional translation services. Less common language pairs may have slightly lower accuracy.

Voice preservation quality is excellent with CosyVoice 2 and GPT-SoVITS, maintaining the speaker's unique tone, pitch, and speaking style across languages. The output sounds like the original speaker naturally speaking the target language.

Yes, batch translation is available through our API. You can submit multiple audio files and receive translated versions of each. This is ideal for translating entire podcast series, video courses, or meeting recordings.

The translated audio maintains similar timing to the original speech, making it suitable for video dubbing. You can also export timestamped transcripts in SRT format to create aligned subtitles in the translated language.

Our API supports near-real-time translation by processing audio in chunks. While not instant, the pipeline can handle live scenarios with a few seconds of delay — useful for multilingual meetings and live presentations.

Yes, our speech translation is suitable for professional dubbing workflows. The voice-preserved output can be used for YouTube localization, e-learning courses, corporate training videos, and film dubbing with further post-production refinement.

Speech translation combines STT, translation, and TTS characters. A typical 1-minute audio translation uses approximately 5,000-10,000 characters depending on the models selected. Free accounts receive 15,000 characters on signup to try the service.

We accept MP3, WAV, OGG, FLAC, M4A, and WEBM files up to 50MB. For best voice preservation results, upload high-quality audio (WAV or FLAC) with clear speech and minimal background noise.

Yes, our speech recognition models handle a wide range of accents including American, British, Australian, Indian English, Latin American and European Spanish, and regional Chinese dialects. The system adapts to the speaker's accent automatically.

The translation engine handles general and domain-specific content well, including medical, legal, technical, and business terminology. For highly specialized content, you can review and edit the intermediate text transcript before generating the translated audio.
