Turning Spanish audio into English text is two jobs, not one — transcribe the Spanish speech into Spanish text first, then translate that text into English. Trustample runs both from a single upload: set the spoken language to Spanish, tick "Translate transcript to English" (Pro), and the finished job holds the Spanish transcript and its English translation together.
Keeping both texts visible is the point. Tools that jump straight from Spanish speech to English hide the transcription step, so a misheard word becomes an invisible translation error nobody can catch — a real risk in exactly the settings this gets used: client interviews, patient conversations, field research, family recordings. With both texts in front of you, verification is mechanical: click any Spanish line to replay that moment, fix a name or number inline, and re-run the translation on the corrected text.
Doing it free: the free plan transcribes 60 minutes a month, so you can get the Spanish transcript at no cost and paste the exported text into any free translator. You lose the stored side-by-side view and subtitle timing, but for a personal recording it genuinely works. The Pro route earns its keep when the English has to be right — or has to become subtitles.
How it works
- 1Set 'Spoken language' to Spanish — and on Pro, set 'Translate transcript to' English.
- 2Upload the audio or video. MP3, M4A, WAV, MP4, MOV and more all work.
- 3Verify against the audio, then export — or read both languages side by side.
Frequently Asked Questions (FAQs)
Can I translate Spanish audio to English text free?
The transcription half is free: 60 minutes a month produce the Spanish transcript, exportable as TXT. Built-in translation is Pro. The honest free workaround: export the Spanish text and run it through any free text translator — two steps, no cost.
How do I translate a Spanish voice recording or voice note?
Same flow — voice memos, WhatsApp audio (export it as a file first) and recorder apps all upload directly, whatever the format. Short notes transcribe in seconds; the English translation sits beside the Spanish text.
Does it handle Latin American Spanish going to English?
Yes — Mexican, Caribbean, Central and South American Spanish all transcribe well, and the translation works from the text, so regional accent doesn't degrade it. Very local slang is the weak spot in both steps; expect to nudge a few phrases by hand.
How accurate is the English translation?
Two error rates stack: transcription (Spanish is among the strongest languages — typically mid-to-high 90s on clear audio) and machine translation, which handles factual spoken Spanish well but flattens idiom and regional expression. Fix the Spanish transcript first; translation errors that begin as hearing errors are the ones nobody catches later.
Can I do Spanish video to English subtitles?
Yes — speech is read straight from video files, so MP4 and MOV upload like audio. Export the Spanish SRT from the transcript's timestamps, and use the stored English translation as the text for an English caption track.
Why can't I just use a translator app on the recording?
Live translator apps are built for short back-and-forth speech, not files — point one at a 40-minute recording and it drifts, drops phrases and saves nothing. Translation tools take text, and a recording isn't text until it's transcribed. That's the whole reason the two-step workflow exists.
An honest note: Machine translation is a working draft, not a certified translation — and for medical, legal or immigration paperwork involving Spanish speakers, a certified human translator is the standard for good reason. What the two-step workflow guarantees is that the draft starts from the right words, and that you can prove it against the audio.
