Swecha Gonthuka Fine-Tuned Telugu ASR

Overview

This repository contains a fine-tuned Automatic Speech Recognition (ASR) model for the Telugu language.

The model is built on Swecha Gonthuka ASR and further fine-tuned using a custom Telugu speech dataset to improve transcription quality and recognition accuracy for Telugu speech.

This model converts spoken Telugu audio into Telugu Unicode text and can be used in a wide range of speech recognition applications.

Usage

Load Processor and Model

from transformers import AutoProcessor, AutoModelForCTC

processor = AutoProcessor.from_pretrained(
    "Vasantha23/swecha-gonthuka-finetuned"
)

model = AutoModelForCTC.from_pretrained(
    "Vasantha23/swecha-gonthuka-finetuned"
)

---

Speech Recognition Pipeline

from transformers import pipeline

pipe = pipeline(
    "automatic-speech-recognition",
    model="Vasantha23/swecha-gonthuka-finetuned"
)

result = pipe("audio.wav")

print(result["text"])

---

Manual Inference

import librosa
import torch
from transformers import AutoProcessor, AutoModelForCTC

processor = AutoProcessor.from_pretrained(
    "Vasantha23/swecha-gonthuka-finetuned"
)

model = AutoModelForCTC.from_pretrained(
    "Vasantha23/swecha-gonthuka-finetuned"
)

speech, sr = librosa.load("audio.wav", sr=16000)

inputs = processor(
    speech,
    sampling_rate=16000,
    return_tensors="pt",
    padding=True
)

with torch.no_grad():
    logits = model(inputs.input_values).logits

predicted_ids = torch.argmax(logits, dim=-1)

transcription = processor.batch_decode(predicted_ids)[0]

print(transcription)

---

Limitations

Performance may decrease in the following situations:

• Heavy background noise
• Low-quality recordings
• Multiple speakers
• Strong regional accents
• Very short audio clips
