Speech to Text API
Integrate our speech recognition technology into your applications
API Overview
Our Speech to Text API allows developers to integrate audio transcription capabilities into their applications. The API supports both file upload and real-time streaming transcription with low latency.
File Upload
Upload audio files in various formats and receive accurate transcriptions with optional word-level timestamps.
Real-time Streaming
Stream audio in real-time and receive transcriptions with low latency for live captioning or voice commands.
Multiple Languages
Supports over 20 languages and dialects with automatic language detection available.
Secure & Scalable
Enterprise-grade security and scalability to handle from small projects to large-scale deployments.

File Upload Endpoint
{
"audio": "base64_encoded_audio_or_url",
"language": "en", // optional
"format": "text", // or "json", "srt"
"timestamps": false // optional
}
{
"status": "success",
"data": {
"transcription": "The transcribed text...",
"language": "en",
"duration": 12.5,
"words": [...] // if timestamps enabled
}
}
Real-time Streaming
Our real-time streaming API uses WebSockets for low-latency transcription. Here's a basic example in JavaScript:
const socket = new WebSocket('wss://api.zmeen.site/v1/stream');
socket.onopen = () => {
// Send authentication
socket.send(JSON.stringify({
token: 'YOUR_API_KEY',
language: 'en'
}));
// Start sending audio chunks
mediaStream.getTracks()[0].onended = () => {
socket.send(JSON.stringify({eof: 1}));
};
};
socket.onmessage = (event) => {
const data = JSON.parse(event.data);
console.log(data.transcript); // Partial transcript
};
Error Handling
The API may return these common error responses:
Invalid or missing API key.
Invalid parameters or unsupported audio format.
Rate limit exceeded.
Server-side issue, try again later.
