Vakgyata

Language Identification for Indian Languages from Speech

---

Model Overview

vakgyata is an open-source language identification model specifically designed to classify Indian languages from raw speech audio. It is built upon the pretrained Harveenchadha/wav2vec2-pretrained-clsril-23-10k with additional Layer Normalization integrated to improve stability and performance for audio classification tasks.

---

Installation

pip install transformers torchaudio

---

Usage

from transformers import Wav2Vec2ForSequenceClassification, AutoFeatureExtractor
import torch

device = "cuda" if torch.cuda.is_available() else "cpu"

model_id = "onecxi/vakgyata-base"  # You can replace with tiny/small/mini variants

processor = AutoFeatureExtractor.from_pretrained(model_id)
model = Wav2Vec2ForSequenceClassification.from_pretrained(model_id).to(device)

---

Inference Example

import torchaudio

# Load the audio (ensure it's 16kHz mono)
audio, sr = torchaudio.load("path/to/audio.wav")

# Preprocess
inputs = processor(audio.squeeze(), sampling_rate=sr, return_tensors="pt").to(device)

# Inference
with torch.no_grad():
    logits = model(**inputs).logits

# Softmax to get probabilities
probs = logits.softmax(dim=-1).cpu().numpy()

# Predicted language
language = model.config.id2label.get(probs.argmax())
print("Predicted Language:", language)
