Whisper Small Armenian v2: Enhanced Fine-tuning for Armenian Speech Recognition

This model is an enhanced fine-tuned version of Chillarmo/whisper-small-armenian on the Chillarmo/common_voice_20_armenian dataset. This v2 model incorporates additional training data and optimizations to achieve improved performance for Armenian automatic speech recognition tasks.

Model Details

Model Description

This is an enhanced fine-tuned Whisper model specifically optimized for Armenian speech recognition. The model builds upon a previously fine-tuned Whisper small model for Armenian and has been further trained with additional data to improve transcription accuracy and robustness for the Armenian language.

• Developed by: Movses Movsesyan (Independent Research)
• Model type: Automatic Speech Recognition
• Language(s): Armenian (hy)
• License: Apache 2.0
• Finetuned from model: Chillarmo/whisper-small-armenian

Model Sources

• Repository: Hugging Face Model Hub
• Base Model: OpenAI Whisper
• Paper: Robust Speech Recognition via Large-Scale Weak Supervision

Uses

Direct Use

This model can be directly used for transcribing Armenian speech to text. It's particularly well-suited for:

• Converting Armenian audio recordings to text
• Real-time Armenian speech transcription
• Building Armenian voice interfaces and applications
• Research in Armenian computational linguistics

Downstream Use

The model can be integrated into larger applications such as:

• Voice assistants for Armenian speakers
• Subtitle generation for Armenian media content
• Accessibility tools for Armenian-speaking communities
• Educational applications for Armenian language learning

Out-of-Scope Use

This model should not be used for:

• Speech recognition in languages other than Armenian
• Speaker identification or verification
• Audio classification beyond speech transcription
• Medical or legal transcription requiring 100% accuracy

Bias, Risks, and Limitations

The model may have limitations including:

• Domain bias: Performance may vary significantly across different speaking styles, accents, and audio quality
• Vocabulary limitations: May struggle with technical terms, proper nouns, or words not present in the training data
• Audio quality dependency: Performance degrades with poor audio quality, background noise, or multiple speakers
• Dialectal variations: May show bias toward specific Armenian dialects represented in the training data

Recommendations

Users should be aware of these limitations and:

• Test the model thoroughly on their specific use case and domain
• Implement appropriate error handling for critical applications
• Consider human review for high-stakes transcription tasks
• Be mindful of potential biases when deploying in diverse linguistic contexts

How to Get Started with the Model

Use the code below to get started with the model:

from transformers import AutoProcessor, AutoModelForSpeechSeq2Seq
import torch

# Load the processor and model
processor = AutoProcessor.from_pretrained("Chillarmo/whisper-small-armenian-v2")
model = AutoModelForSpeechSeq2Seq.from_pretrained("Chillarmo/whisper-small-armenian-v2")

# Process audio
def transcribe_armenian(audio_path):
    # Load and process audio file
    import librosa
    audio, sr = librosa.load(audio_path, sr=16000)
    
    # Process the audio
    inputs = processor(audio, sampling_rate=16000, return_tensors="pt")
    
    # Generate transcription
    with torch.no_grad():
        predicted_ids = model.generate(inputs["input_features"])
    
    # Decode the transcription
    transcription = processor.batch_decode(predicted_ids, skip_special_tokens=True)
    return transcription[0]

# Example usage
# transcription = transcribe_armenian("path/to/armenian_audio.wav")
# print(transcription)

Training Details

Training Data

The model was fine-tuned on the Chillarmo/common_voice_20_armenian dataset with additional training data incorporated to enhance performance and robustness. This v2 version represents an iterative improvement over the base fine-tuned model, with expanded training data to better capture Armenian speech patterns and vocabulary.

Training Procedure

Training Hyperparameters

The following hyperparameters were used during training:

• Training regime: Mixed precision training
• Epochs: 5.24
• Training runtime: 44,426 seconds (approximately 12.3 hours)
• Training samples per second: 1.801
• Training steps per second: 0.113
• Final training loss: 0.076

Speeds, Sizes, Times

• Training time: ~12.3 hours for 5000 training steps
• Evaluation time: ~2.6 hours for evaluation
• Evaluation samples per second: 0.624
• Total training steps: 5,000

Evaluation

Testing Data, Factors & Metrics

Testing Data

The model was evaluated on a held-out test set from the Chillarmo/common_voice_20_armenian dataset.

Metrics

The model was evaluated using standard speech recognition metrics:

• Word Error Rate (WER): Measures the percentage of words that are incorrectly transcribed
• Character Error Rate (CER): Measures the percentage of characters that are incorrectly transcribed
• Exact Match: Percentage of utterances that are transcribed perfectly

Results

The fine-tuned model achieved the following performance on the evaluation set:

Metric	Value
Word Error Rate (WER)	24.01%
Character Error Rate (CER)	4.77%
Exact Match	28.14%
Average Prediction Length	7.74 tokens
Average Label Length	7.77 tokens
Length Ratio	0.995

Summary

The model demonstrates strong performance for Armenian speech recognition with a relatively low character error rate of 4.77% and word error rate of 24.01%. The length ratio close to 1.0 indicates that the model generates transcriptions of appropriate length compared to the ground truth.
