TOOLGENIEHow to Use the Speech to Text Converter
Basic Mode (Browser)
- Select your language from the dropdown — 14+ languages supported.
- Click the blue microphone button and grant microphone permission when prompted.
- Speak clearly — words appear in real-time as you talk.
- Click the stop button when finished, then copy or download your transcript.
Advanced Mode (AI-Powered)
- Choose your AI model — Whisper Large v3 Turbo is recommended for most uses; Large v3 gives maximum accuracy for complex speech.

About the Free Speech to Text Converter
ToolGenie's Speech to Text Converter offers two transcription modes in one tool. Basic mode uses your browser's built-in Web Speech API for instant, real-time transcription with no uploads or processing delay — ideal for quick dictation and voice notes.
Advanced mode is powered by OpenAI's Whisper Large v3 running on Groq's ultra-fast inference platform, delivering significantly higher accuracy — especially for accented speech, technical vocabulary, and noisy environments. After transcription, an AI language model automatically formats the output: removing filler words, adding proper punctuation, and organizing text into readable paragraphs.
Advanced mode also supports audio file uploads (MP3, WAV, M4A, WEBM, FLAC, and more), so you can transcribe recorded meetings, interviews, lectures, or podcasts directly — not just live microphone input. All audio is processed securely via the API and is not stored.
Frequently Asked Questions (FAQ)
1. What is the difference between Basic and Advanced mode?
Basic mode uses your browser's built-in Web Speech API for instant real-time transcription — words appear as you speak, no uploads needed. It works in Chrome, Edge, and Safari. Advanced (AI) mode records audio and sends it to OpenAI Whisper running on Groq for significantly higher accuracy, supports audio file uploads, live dictation, text paste with AI formatting, and works in any browser including Firefox.
2. Can I upload an audio file to transcribe?
Yes — switch to Advanced mode and click the Upload tab. Drag and drop or browse for your audio file. Supported formats include MP3, MP4, M4A, WAV, WEBM, OGG, FLAC, and MPEG up to 25 MB. This lets you transcribe recorded meetings, interviews, lectures, and podcasts directly.
3. How accurate is the AI speech to text?
Advanced mode uses OpenAI Whisper Large v3 Turbo, which achieves 95–99% word accuracy for clear speech. It handles accented speech, technical vocabulary, and moderate background noise far better than browser-based transcription. For maximum accuracy on difficult audio, switch to Whisper Large v3 in the model selector.
4. What does AI Post-Processing do?
After transcription, an AI language model (Llama 3.1 via Groq) reformats the raw transcript by adding proper punctuation and capitalization, removing filler words ("um," "uh," "like," "you know"), fixing grammar mistakes, and organizing text into clear paragraphs. The Raw tab always shows the original unedited transcript so you can compare.
5. What is the Paste tab for?
The Paste tab lets you paste or type any existing text — from emails, meeting notes, rough drafts, or web pages — and click Format Notes to clean it up with AI. It fixes punctuation, removes filler words, and organizes text into readable paragraphs, all without any audio recording.
6. Which languages are supported?
Basic mode supports 14+ language variants including English (US/UK), Spanish (Spain/Mexico), French, German, Italian, Portuguese (Brazil), Chinese (Mandarin), Japanese, Korean, Arabic, Hindi, and Russian. Advanced mode supports all Whisper languages with an Auto-detect option that identifies the spoken language automatically — no manual selection needed for multilingual recordings.
7. Is my audio or speech data stored?
ToolGenie does not store your audio, speech, or transcripts. In Basic mode, audio is processed entirely inside your browser and never leaves your device. In Advanced mode, audio is sent to Groq's API (using OpenAI Whisper) for transcription only and is not retained after processing. Your transcript text is never stored on ToolGenie's servers.
8. How do I get the best transcription results?
Use a headset or external USB microphone instead of a built-in laptop mic, minimize background noise, speak at a moderate pace, and select the correct language (or use Auto-detect). Position your mic 6–12 inches from your mouth and slightly to the side to avoid plosive sounds. For long recordings or noisy environments, Advanced mode with Whisper will always outperform the browser's Basic mode.
Tips for Better Speech Recognition
- Use a headset or external microphone: Built-in laptop mics work, but a USB or Bluetooth headset provides cleaner audio and dramatically better accuracy.
- Find a quiet space: Background music, air conditioning, and other voices interfere with both Basic and Advanced transcription.
- Speak at a moderate pace: Don't rush — clear, deliberate speech gives the model time to process each word correctly.
- Use Advanced mode for long recordings: Record an entire meeting or lecture, then let the AI clean it up — far more efficient than live Basic mode for extended sessions.
- Upload pre-recorded audio: The Upload tab in Advanced mode lets you transcribe existing audio files such as interviews, podcasts, or voice memos without re-recording.
- Toggle AI formatting off when needed: If you want an exact verbatim transcript (including pauses and filler words), disable AI Post-Processing and view the Raw tab.
- Select your language explicitly: While Auto-detect is convenient, manually selecting the language can improve accuracy for short recordings or heavily accented speech.
