Dub American English Videos to Thai

Translation converts words from one language to another. Every SpeakSwap dub is powered by SpeakSwap Localization AI™, which understands who’s speaking, who they’re talking to, which words matter, and whether the tone should be casual or formal, then creates a script that feels natural in the target language. Different languages have different speaking speeds, idioms, and cultural expressions. SpeakSwap uses surrounding context to choose more natural phrasing, adapts pacing so speech fits the original timing as closely as possible, and clones the speaker's voice so the result feels like a localized version of the same video.

A typical 5-minute video takes about 5-10 minutes to process. Longer videos take longer, but the pipeline is built for creator content: transcription, localization, timing calibration, voice cloning, and final mixing all run together so translated speech stays aligned with the original video.

SpeakSwap supports 70+ target languages in its dubbing workflow. Voice cloning is available in the workflow. Voice availability and output quality vary by target language, source audio, and selected voice. Test a short sample for your exact language pair.

SpeakSwap supports 70+ target languages. Voice choices and output quality vary by language and selected voice, so test a short sample before a large project.

In supported media, yes. SpeakSwap separates speech from background audio, dubs the spoken parts, then mixes the new voice back with the original background audio so the video still feels like the source.

Yes. Sign up is free and gets you 20 starter credits to try every tool. Credits are used across the whole platform, and $6 adds 600 credits. No subscription required.

Yes. Give your best speaker-count estimate before submitting so SpeakSwap can separate the audio. In reviewed lip-sync jobs, your final script assignments become the source of truth for each voice-clone path. Podcasts, interviews, panels, gaming co-op commentary, and roundtable clips are supported; very heavy overlap can still need cleanup.

SpeakSwap generates Thai speech with tonal pronunciation, but results vary with the source audio, wording, and selected voice. Review a short sample, especially for names, regional wording, and tone-sensitive phrases.

Yes. In video dubbing, smart lip sync is optional for eligible clips longer than 20 seconds and up to 90 seconds. SpeakSwap detects speakers and recurring faces, then asks you to confirm speaker-to-face matches before rendering. It is designed for real talking-head video with visible, moving faces — not a still image, slideshow, or image-to-video animation. Transcription, text-to-speech, and other audio-only tools continue to work without lip sync.

Use real talking-head footage where a person is visibly speaking and the face moves naturally. SpeakSwap can dub a still-image video as audio, but it does not animate still pictures, slideshows, or image-to-video portraits. Turn smart lip sync off for those sources and use the audio dub instead.
