Translate Spanish Audio to English

Spanish over the phone

Voicemail and call audio carries a narrow band of frequencies, far less than a microphone recording. Consonants at the ends of words are the first thing to blur, and many Spanish speakers already soften them: in Caribbean and Andalusian Spanish a final "s" often becomes a breath or disappears ("los amigos" heard as "lo amigo"), and a final "d" drops ("verdad" as "verdá"). On a clear recording the transcript usually restores the full words; on a phone line it guesses more often, and a wrong Spanish word becomes a wrong English one. When a voicemail matters, read the Spanish transcript too, not only the English. Transcribing phone call recordings covers phone audio in more depth.

Getting the message off the phone

1. iPhone voicemail: open the message in the Phone app, tap the share button and save or send it. It arrives as an M4A file, which uploads as it is.
2. Google Voice: download the voicemail from the web app; it saves as MP3.
3. WhatsApp voice notes saved as .opus files aren't accepted. Convert them to MP3 or M4A in any audio converter first.
4. Android call recorders and voicemail apps often save .amr or .3gp files, which also need converting first.
5. A Spanish video, such as a clip someone filmed, goes to the Spanish to English video translator, which also covers Spanish surnames, numbers and timing.

Who receives Spanish recordings

A working copy, not a certified translation

Court filings, immigration applications and official records need a certified translation, signed by a human translator who vouches for it. A machine translation can tell you what a recording says, help you decide whether it needs a certified translation, and give the translator a head start, but it can't replace one. Certified translation versus an AI transcript sets out when each is appropriate.

Two voices on one call

Transcripts don't carry speaker names. In a two-person call, or a focus group with several voices, the English reads as one continuous text with timestamps. Add names yourself while listening, using the timestamps to jump to each change of speaker. Services that label speakers exist; if names are essential, use one of those or plan the extra pass. What speaker diarization is explains the technique.

Read it or hear it in English

English text is enough for nearly every voicemail and most interviews. An English voice track suits a Spanish podcast, a testimonial or a talk you want to publish: up to 8 speakers are told apart, and each speaks English in a copy of their own voice, over the original background sound. English usually takes fewer syllables than Spanish, so the English lines rarely need speeding up and sometimes leave short pauses where the Spanish ran longer.

Costs for short messages and long recordings

English text costs 1 credit per minute with a 5-credit minimum; an English voice costs 50 credits per minute with a 2-minute minimum. The 100 free credits from signing in with Google cover 20 short voicemails at the minimum. Top-ups are charged in Indian rupees at the day's exchange rate through Cashfree Payments (UPI, cards or netbanking), about ₹96 for 1,000 credits.

Spanish that switches into English

US recordings often move between Spanish and English inside one sentence. Both languages are written as spoken in the transcript, and the English translation carries the English parts through. Mixed sentences produce more errors than pure Spanish, so read them against the audio. Translating mixed-language videos explains why, and the same applies to recordings.

Using the tool on this page

• The spoken language is detected automatically; you select the output language — the spoken language itself for an untranslated transcript, or another language for a translation. Files can be up to 2 hours long.
• Audio is sent over HTTPS in small chunks and deleted with its transcripts within 30 minutes of delivery (how files are protected).
• You can download a timestamped transcript, subtitles (SRT and VTT) and plain text. Every output, step and limit is explained on the audio translator page.
