Ratan Tata SpeechT5 Voice Cloning Model

This model is a Text-to-Speech (TTS) system using SpeechT5 architecture, trained on the Ratan Tata TTS Dataset to generate high-quality synthetic speech resembling the voice of Ratan Tata. The dataset and model pay tribute to his legacy, preserving his voice through cutting-edge AI technology.

Model Information

Model Architecture: SpeechT5 (Text-to-Speech)
Training Dataset: Ratan Tata TTS Dataset (English)
Checkpoints: 60,000 steps
Framework: PyTorch
Model Size: Approximately 1.9GB
License: OpenRAIL

Dataset Summary

This model was trained on over 2,800 seconds (~48 minutes) of high-quality speech samples from Ratan Tata, with detailed transcriptions for each audio file. The audio data was pre-processed, converted to a uniform format, and aligned with the corresponding text to ensure optimal training performance.

Model Performance

Voice Quality: The model replicates the unique tone, cadence, and voice texture of Ratan Tata with high accuracy, making it suitable for various voice cloning applications.
Sample Rate: 16 kHz (consistent with the training data)
Audio Channels: Mono
Bit Depth: 16-bit
Precision: High-quality synthesis using SpeechT5

How to Use the Model

You can use this model for a variety of TTS and voice synthesis tasks. It is designed to work with any standard TTS pipeline and can be integrated into projects for generating Ratan Tata’s voice in any text-based scenario.
