Frequently Asked Questions

What is the difference between speech translation and video dubbing?

Speech translation focuses on translating the audio track of a video and replacing it with a natural AI voice in the target language. Video dubbing may additionally include lip sync alignment. Curify's speech translator produces a dubbed video with the translated voice track.

Which languages are supported?

Curify supports 170+ languages including English, Spanish, French, German, Chinese, Japanese, Korean, Arabic, Hindi, and many more. Language detection is automatic.

What Is AI Speech Translation?

AI speech translation converts spoken words in a source language into natural spoken words in a target language — generating a new audio track in the translated language rather than displaying text subtitles.

The output is a dubbed video: the original video with its audio replaced by a translated, AI-synthesized voice. This is the fastest way to make video content natively accessible to international audiences without requiring a recording studio.

Curify's speech translator is designed for real-world video content — handling background noise, multiple speakers, technical vocabulary, and natural conversational pacing across 170+ languages.

How Curify Translates Speech

Curify's speech translation pipeline combines high-accuracy transcription, context-aware translation, and natural voice synthesis in a single automated workflow.

Step 1: Speech is transcribed from the source audio using production-grade speech recognition that handles accents, domain vocabulary, and multi-speaker dialogue.

Step 2: The transcript is translated using context-aware models that preserve meaning, tone, and intent — not just literal word substitution.

Step 3: A natural AI voice synthesizes the translated text in the target language, matching the original pacing and emotional delivery where possible.

Step 4: The synthesized voice track replaces the original audio in the video, and you receive a fully dubbed video file ready to publish.
