Implement Qwen2.5-Omni-7B using AutoModel as per Hugging Face documentation

README.md

 # Audio Transcription App
 
-This Python application transcribes audio files with speaker diarization and timestamps using Whisper and Resemblyzer models.
+This Python application transcribes audio files with speaker diarization and timestamps using Qwen2.5-Omni-7B and Resemblyzer models.
 
 ## Features
 - Automatic speech recognition with Qwen-Omni-7B (4-bit quantized)
