How to Convert Voice to Text in Real Time
ChatGPT cannot provide live captions for meetings or events because it only processes text input. ChatGPT cannot listen to live audio streams, display real-time captions, or generate ADA-compliant subtitle overlays. This live transcription tool captures speech directly from your microphone or system audio with sub-300ms latency.
Gemini cannot generate real-time captions from live audio. Google Gemini handles text and image input but cannot process continuous audio streams or display synchronized captions during meetings, lectures, or live events. This tool provides instant speech-to-text with automatic speaker identification and export to SRT format.
The live audio to text converter turns speech into text instantly. It works for meetings, lectures, interviews, and live events across 30+ languages. Transcription runs on Whisper Large-v3 via Groq inference; per-language word error rates are documented on the accuracy page.
Converting voice to text happens automatically with no setup required. The tool provides free live captions that can be exported in SRT for ADA and WCAG caption workflows in professional and educational settings.
Key capabilities:
- Real-time speech to text with sub-300ms first-word latency
- Automatic punctuation and formatting

The converter captures audio in the browser and streams it to our managed inference for transcription. Audio is processed and not retained for training. First-word display latency is typically under 300 ms on a modern laptop and broadband connection.
Live-caption coverage by platform
Live captioning depends on the browser’s ability to capture system audio plus the speech model’s processing window. Coverage and latency vary by platform.
| Platform | Live captions supported | Browser requirement | Typical latency |
|---|---|---|---|
| Zoom (web client) | Yes | Chrome, Edge, Firefox latest | 1-2 sec |
| Google Meet (web) | Yes | Chrome, Edge | 1-2 sec |
| Microsoft Teams (web) | Yes | Chrome, Edge, Firefox | 2-3 sec |
| Generic browser audio (any tab) | Yes | Chrome, Edge | 1-2 sec |
| Native desktop apps | No, use web version | n/a | n/a |
| Mobile browser | Limited | Chrome on Android | 2-4 sec |
Latency is end-to-end from spoken word to displayed caption. For ADA/WCAG compliance the W3C suggests captions arrive within 1 second of the spoken word for live events. Chrome on a modern laptop running the web client meets that bar on Zoom and Google Meet. Latency on Teams runs slightly higher because Teams uses Opus at a lower bitrate inside the browser. For per-language accuracy figures behind these latencies, see the accuracy page.

How accurate is real time transcription?
Transcription runs on Whisper Large-v3, the open-weight model from OpenAI, served on Groq inference. Word error rate varies by language and audio quality; per-language WER and the rest of the model stack are on the accuracy page. For reference, Rev AI publishes 98% on broadcast English and Otter publishes 95% on clean meeting audio. ScreenApp does not claim a single blanket accuracy number because it depends on which language and what the recording sounds like.

What file formats can I export transcripts to?
Download completed transcripts in TXT, DOCX, PDF, and SRT formats. The live audio to text converter preserves speaker labels, timestamps, and formatting in all export formats. Perfect for meeting minutes, subtitle files, compliance documentation, and archival records.
Does the live audio to text converter work with Zoom and Google Meet?
Yes, the browser-based tool captures system audio from Zoom, Google Meet, Microsoft Teams, and any other video conferencing platform. Unlike bot-based competitors, it works invisibly without joining your meeting as an extra participant. No permissions or installations required.
How fast is real time transcription?
The live audio to text converter delivers captions within 200-300 milliseconds of speech. This is faster than Otter.ai (1-2s), Fireflies.ai (2-3s), and Notta (1-2s). Sub-second latency ensures live captions stay synchronized with speakers for immediate accessibility.
