AI Speech to Text
Convert audio and video recordings into text, with speaker separation and downloadable transcripts.
◆ VOICE AND SPEECH TOOLS
Speech and text are the same content in two forms. These tools move between them in both directions, so a meeting can become notes and a document can become something you listen to.
Tools in this category
Transcription turns what was said into something searchable. Synthesis turns what was written into something people can listen to while doing something else.
Convert audio and video recordings into text, with speaker separation and downloadable transcripts.
Turn written text into natural AI speech and download the audio.
Narrate a PDF or EPUB book chapter by chapter and produce a finished audiobook.
Master a finished recording to broadcast loudness: normalise to −16 or −14 LUFS, trim the silent ends and add fades.
Convert a recording between MP3, WAV, M4A, OGG and FLAC with control over bitrate and quality, keeping the tags.
Clean a script, write numbers out in words and see how many speech requests it needs — all in your browser.
Measure the steady hum under a recording — air conditioning, a fan, hiss — then remove it without moving the speech level.
Turn a long episode into 15-second clips cut around its loudest moments, with a mashup and JSON metadata in one ZIP.
Put an AI voice-over onto an existing video, with timed captions if you need them.
Summarise a long recording or document into a structured overview rather than a full transcript.
Take a subtitle file produced from speech and translate it into another language.
Choosing between them
If the recording already exists, start with speech to text. If the words already exist and need a voice, start with text to speech or the audiobook creator. If you only need the gist rather than every sentence, the summarizer will save you the most time.
Whichever direction you are going, the tool that does it is one click away.
