Mexican Spanish Subtitles: upload audio or video and get captions or a transcript that keep the regional words and accent. Edit, then export SRT or TXT.
Free for recordings up to 1 hour and 1 GB. Longer files need a paid plan.
How It Works
Drop an audio or video file — MP4, MOV, MP3, WAV, M4A and more. The language is already set to Spanish.
AssemblyAI transcribes every word with exact timings — usually a fraction of the recording's length.
Copy the text or download SRT, VTT and TXT files.
The Mexican Spanish Subtitles is a free online tool from ShortsHero: slang and accent kept, not flattened. AssemblyAI speech recognition does the work — a 5-minute recording usually comes back in under 30 seconds. It is free for files up to 1 hour with no watermark; longer recordings need a paid plan.
Spanish is in AssemblyAI's high-accuracy tier, with a typical word error rate of 10% or less on clear speech. Spanish also runs on AssemblyAI's newest Universal-3.5 Pro model, which handles regional accents and mixed-language speech.
Free transcription covers files up to 1 hour. If your recording is longer, a paid plan lifts the limit — or trim it into parts and run each one.
Why Use This Tool
Every word carries its start and end time, so subtitles line up with the speech.
The formats YouTube, Premiere, Resolve, CapCut and every major player accept.
Filter the transcript on the page to find any word and jump to its timestamp.
Full recordings, not a one-minute sample. Paid plans lift the length limit.
The language is set to Spanish, so the AI never guesses wrong on a short or noisy clip.
Use the files anywhere — the transcript and subtitles are yours.
Yes. Files up to 1 hour long are free, with no watermark and no account needed. Recordings longer than 1 hour need a paid ShortsHero plan.
Spanish is in AssemblyAI's high-accuracy tier, with a typical word error rate of 10% or less on clear speech. Spanish also runs on AssemblyAI's newest Universal-3.5 Pro model, which handles regional accents and mixed-language speech. Accuracy drops with music, crosstalk and distant microphones, so check names and technical terms before you publish.
MP4, MOV, WebM, MKV, MP3, WAV, M4A, AAC, OGG, FLAC and most other audio and video formats, up to 1 GB. For a long video, uploading just the audio is faster.
Yes. Download the SRT and open it in our free online SRT editor, or in any video editor, to fix a word or a timing.
Usually well under the length of the recording — a 10-minute file is typically done in about a minute.
ShortsHero turns long videos into short vertical clips with AI moment detection, face tracking and animated captions — and has free tools for subtitles, transcripts and video formats.
The same transcription powers ShortsHero's clip maker: it finds the strongest moments, reframes them to vertical and adds word-by-word captions in 36 styles.
