Speech, Audio and Lettering Tools
These tools move words between text, voice and visual lettering: Text to Speech reads pasted text aloud, Speech to Text turns your dictation into editable text, the Audio Format Converter decodes MP3, M4A, FLAC, OGG and WebM into WAV, and the Calligraphy Font Generator previews a phrase in 51 script and display fonts. Writers proofreading by ear, people dictating drafts, podcasters and developers preparing audio for speech models, and anyone choosing a font for an invitation use them.

All Text/Speech Tools (4)
Which tool do I need?
Listen to an article instead of reading it
Paste the text, choose a local voice and set the speed. Shorter chunks avoid cut-offs with some online voices.
Dictate a draft email or notes
Pick your exact language variant, press the microphone and edit the transcript before copying it.
Convert an MP3 or M4A to WAV for an audio editor or speech model
Drop the files, choose a sample rate and mono or stereo, and download each WAV.
Pick a script font for an invitation or a logo
Type the phrase once and compare it in 51 calligraphy, handwritten and decorative fonts.
About Text/Speech Tools
The speech tools both rely on the Web Speech API built into your browser, so what you get depends on the browser and operating system. Voices for reading aloud are the ones your system already has, and dictation works in Chrome, Edge and Safari but not Firefox. The audio converter is a practical companion when you feed recordings to other software: many speech recognition engines and audio editors prefer plain WAV, often at 16 kHz mono. For timestamps and clocks, see Time Utilities; for encoding text, see Encoding Tools.
Privacy differs between the tools. Speech to Text may not run offline: depending on the browser and its settings, recognition can happen on a vendor's servers (Chrome and Edge typically use them) rather than on the device. Text to Speech voices labelled "online voice" send your text to a cloud service, while the rest run locally. The audio converter decodes in your browser and uploads nothing, but it only writes WAV and cannot read WMA. The calligraphy previews are real web fonts from Google Fonts, so copied text pastes as plain text.

Frequently asked questions
Is browser speech recognition private?
Not fully. Browsers send dictated audio to their vendor's recognition service, such as Google for Chrome. Avoid dictating passwords, health details or anything confidential.
Why are the text to speech voices different on each computer?
The voices come from the operating system and browser, not from the website. Windows, macOS, Android and Chrome each install their own set, so the same page offers different lists.
Why convert audio to 16 kHz mono WAV?
Many speech recognition models and transcription tools expect that format, and WAV avoids a second lossy decode step. Keep 44.1 or 48 kHz stereo for music and editing.
Can I paste calligraphy text into Instagram or Word?
You can paste the words, but they arrive in the destination's default font. The previews use real web fonts, so install or select the same font by name to reproduce the look.
