Wispr Flow Hello World

Overview

Stream audio to Wispr Flow and receive real-time transcription. Wispr specializes in developer-context-aware dictation -- it understands code terms, CLI commands, and technical jargon.

Instructions

Step 1: Record and Transcribe (REST)

import requests, os

# Transcribe an audio file
with open("voice-memo.wav", "rb") as audio:
    response = requests.post(
        "https://api.wisprflow.ai/api/v1/transcribe",
        headers={"Authorization": f"Bearer {os.environ['WISPR_API_KEY']}"},
        files={"audio": audio},
        data={"language": "en", "context": "programming"},
    )

result = response.json()
print(f"Text: {result['text']}")
print(f"Confidence: {result.get('confidence', 'N/A')}")

Step 2: Real-Time Streaming (WebSocket)

// Stream microphone audio to Wispr Flow
const ws = new WebSocket('wss://api.wisprflow.ai/api/v1/ws');

// Browser audio capture
const stream = await navigator.mediaDevices.getUserMedia({ audio: true });
const context = new AudioContext({ sampleRate: 16000 });
const source = context.createMediaStreamSource(stream);

const processor = context.createScriptProcessor(4096, 1, 1);
source.connect(processor);
processor.connect(context.destination);

processor.onaudioprocess = (event) => {
  const audioData = event.inputBuffer.getChannelData(0);
  // Convert Float32Array to Int16Array for transmission
  const int16 = new Int16Array(audioData.length);
  for (let i = 0; i < audioData.length; i++) {
    int16[i] = Math.max(-32768, Math.min(32767, audioData[i] * ));
  }
  ws.(int16.);
};

ws. =  {
   data = .(event.);
   (data. === ) {
    .();
  }   (data. === ) {
    .();
  }
};

Output

Partial: implement a function that
Final: Implement a function that calculates the Fibonacci sequence using dynamic programming.

Error Handling

Error	Cause	Solution
Garbled text	Wrong sample rate	Use 16kHz mono PCM
No results	Silence or noise	Check microphone input
High latency	REST endpoint	Use WebSocket for streaming
