iVaani

iVaani - Fine-tuned ASR model for Hindi Language

Model Description

This is iVaani model, specifically optimized for the Hindi language. The fine-tuning process has led to an improvement in accuracy by 2.5% compared to the original Whisper model.

Performance

After fine-tuning, the model shows a 2.5% increase in transcription accuracy for Hindi language audio compared to the base Whisper medium model.

How to Use

You can use this model directly with a simple API call in Hugging Face. Here is a Python code snippet for using the model:

from transformers import AutoModelForCTC, Wav2Vec2Processor

model = AutoModelForCTC.from_pretrained("rukaiyah-indika-ai/iVaani")
processor = Wav2Vec2Processor.from_pretrained("rukaiyah-indika-ai/iVaani")

# Replace 'path_to_audio_file' with the path to your Hindi audio file
input_audio = processor(path_to_audio_file, return_tensors="pt", padding=True)

# Perform the transcription
transcription = model.generate(**input_audio)
print("Transcription:", transcription)

Additional Language Models

Indika AI has also fine-tuned ASR (Automatic Speech Recognition) models for several other Indic languages, enhancing the accuracy by 2-5% for each language. The word error rate has also been significantly reduced.

The additional languages include:
