Model description
The IshanSuga/whisper-small-si-bank-v3 model is an Automatic Speech Recognition (ASR) system fine-tuned on Sinhala speech data, specifically tailored for banking-related conversations. Built upon OpenAI’s Whisper-Small architecture, this model leverages transfer learning to enhance transcription accuracy for Sinhala audio.
Key Features:
Pretrained Foundation: Based on OpenAI’s Whisper-Small, a robust ASR model trained on a large multilingual dataset.
Fine-tuned for Sinhala: Adapted using domain-specific Sinhala banking conversations to improve transcription quality in financial settings.
Intended uses & limitations
Use Cases:
Banking Chatbots & Assistants – Enables automated customer service and inquiry handling.
Speech-to-Text Applications – Converts Sinhala speech into text for documentation and accessibility.
Financial Call Center Analytics – Helps in analyzing and transcribing customer interactions.
