Supertranslate

Supertranslate is a cloud-based speech-to-text and subtitle generation platform designed for media professionals, content creators, and organizations that need to process audio and video content at scale. The platform converts spoken language into accurate text transcriptions, automatically generates subtitles in multiple formats, and provides machine translation for global distribution. It supports over 125 languages and dialects, including regional variants, making it suitable for international workflows. The core functionality relies on an advanced automatic speech recognition (ASR) engine that handles various accents, background noise, and field recordings. It can differentiate multiple speakers in a conversation (speaker diarization) and assign labels to each speaker in the transcript. The system is optimized for processing speed: one hour of audio is typically transcribed in about two minutes, allowing rapid turnaround for large volumes of media. Users can upload audio or video files in common formats (e.g., MP3, WAV, MP4, MOV) through a web interface or via an API for batch processing. Once uploaded, the platform automatically transcribes the speech, creates a timestamped transcript, and offers options to generate subtitle files in formats such as SRT, VTT, ASS, or plain text. The subtitles can be further edited in a built-in editor that adjusts timing, splits or merges segments, and corrects transcription errors. For multilingual projects, Supertranslate provides machine translation that preserves subtitle timing and segmentation, enabling one-click generation of subtitles in dozens of target languages. The platform is particularly useful for video editors, translators, educators, podcasters, and corporate training departments. For example, a YouTube creator can
