VOICE TO TEXT
Step 1: Install the AI Library
Stop your server if it’s running, and install the new requirements in your terminal:
Bash
pip install fastapi uvicorn python-multipart faster-whisper
Step 2: The Backend (main.py)
We will create a new endpoint that accepts an audio file from the website, feeds it to the Whisper AI, and returns the transcribed text.
Python
from fastapi import FastAPI, UploadFile, File
from fastapi.middleware.cors import CORSMiddleware
from faster_whisper import WhisperModel
import os
import uuid
app = FastAPI()
# Enable CORS for the frontend
app.add_middleware(
CORSMiddleware,
allow_origins=[“*”],
allow_credentials=True,
allow_methods=[“*”],
allow_headers=[“*”],
)
# Load the AI Model. “base” is fast and accurate enough for most CPUs.
# It will automatically download the model the first time you run this script.
print(“Loading AI Model… This may take a minute the first time.”)
model = WhisperModel(“base”, device=”cpu”, compute_type=”int8″)
print(“AI Model Ready!”)
@app.post(“/transcribe”)
async def transcribe_audio(audio: UploadFile = File(…)):
# Save the incoming audio file temporarily
filename = f”{uuid.uuid4()}.webm”
with open(filename, “wb”) as buffer:
buffer.write(await audio.read())
try:
# Ask the AI to transcribe the audio
# It automatically detects the language (English, Tamil, etc.)
segments, info = model.transcribe(filename, beam_size=5)
# Combine all transcribed segments into one paragraph
transcription = ” “.join([segment.text for segment in segments])
# Delete the temporary audio file to save space
if os.path.exists(filename):
os.remove(filename)
return {
“text”: transcription.strip(),
“detected_language”: info.language
}
except Exception as e:
if os.path.exists(filename):
os.remove(filename)
return {“error”: str(e)}
Step 3: The Frontend (index.html)
This HTML file uses your browser’s built-in microphone to record audio. When you stop recording, it packages the audio and sends it to the FastAPI backend.

Step 4: How to Run It
- Start your backend using the bypass method:
Bash
python -m uvicorn main:app –reload
- Open your index.html file in a web browser.
- Click Start Recording (your browser will pop up asking for permission to use the microphone. Click Allow).
- Speak clearly into your mic (try English or Tamil!).
- Click Stop & Transcribe. Within a few seconds, the Whisper AI will process the audio locally on your machine and type out exactly what you said.
