Spanish dubbing is useful for tutorials, explainers and YouTube clips whose speech is already transcribed in an English SRT.
Download or create a timestamped .srt file for the video. If you need one, use the YouTube transcript downloader. Check that captions are in order and end within 40 minutes.
Choose a Spanish voice sample before starting. The available voices may have different regional pronunciation, so listen for the accent your audience expects.
Open the tool with English and Spanish selected. Hear the available voices, choose one, then start the job. The queue position and progress remain available after a page refresh. Voices labeled Online send translated text to Microsoft's speech service.
Example spoken line in Spanish:
Hola. Esta es una muestra de audio doblado.
Spanish translations can be longer than the original English line. Edit crowded subtitles into shorter sentences if the preview sounds rushed.
Download the MP3 and translated SRT. Put the MP3 on your video's audio track in an editor and review synchronization. The tool generates speech from subtitles; it does not preserve original music, clone a speaker, or export a merged video.
