Step-by-step guide

How to Use Speech to Text

Start for free — no credit card, no software to install.

  1. Upload your audio

    Add an MP3, WAV or other common audio file from your device — no recording tool built in, just a file you already have.

  2. Let language auto-detect, or set it

    Leave language on auto-detect for most recordings, or choose the language yourself when a file mixes accents or technical terms.

  3. Get transcript and duration back

    Once the job finishes you receive plain text and the clip's duration — copy it out or download it, nothing more, nothing timed.

Speech to Text

Features & Capabilities

Everything you need to create professional voiceovers — in one tool.

  • Plain text output

    You get the words as text and the file's duration — nothing timed, no subtitle format.

  • Automatic language detection

    The engine identifies the spoken language on its own, with an optional manual override.

  • Duration limits by plan

    Free files run up to 20 minutes; Lite 1 hour, Pro 3 hours, Max 6 hours per upload.

  • Asynchronous processing for long files

    Submit a long recording and come back — it processes as a background job instead of holding a page open.

Use cases

What Can You Create with Speech to Text?

From TikTok to podcasts — here's where creators use this tool most.

  • Turning a recording into readable notes

    Convert a voice memo, lecture or call into a text file you can skim, search and paste into a document.

  • Building a searchable archive of audio

    Run a backlog of recordings through the tool so their content shows up in a text search instead of staying locked inside audio files.

  • Drafting article text from spoken content

    Start from a rough transcript and edit it down into publishable copy, rather than typing up a recording from scratch.

  • Checking what was actually said

    Get an exact text record of a recorded conversation when memory or shorthand notes aren't reliable enough.

About this tool

Everything you need to know about Speech to Text

Speech to text on VocalLab takes an audio file and gives back exactly two things: a plain text transcript and the file's duration. There are no captions, no SRT or VTT files, and no word-by-word timestamps — if you need the words, not a timed subtitle track, this is built for that. Language is detected automatically, or you can point it at a specific language if the recording mixes accents or terms. How long a single file can run depends on your plan: 20 minutes free, 1 hour on Lite, 3 hours on Pro, and up to 6 hours on Max. Longer files are queued as a background job rather than making you wait on a spinner.

FAQ

Speech to Text — FAQ

Something not covered here? Contact us · support@vocallab.ai

Does speech to text produce captions or subtitles?

No — the output is a plain text transcript and a duration, with no timing data, so it can't be used directly as an SRT or VTT file.

How long can a file be?

It depends on your plan: 20 minutes on Free, 1 hour on Lite, 3 hours on Pro and 6 hours on Max, per uploaded file.

Does it label who is speaking?

No, there are no speaker labels — a recording with several voices comes back as one continuous block of text.

What happens with a very long recording?

It runs as a background job rather than a live wait, so a multi-hour file can take a few minutes to finish processing after you submit it.

Do I need to set the language manually?

Usually not — language is detected automatically, though you can specify one yourself if a recording mixes languages or has technical vocabulary.
