Trigger fresh build - update README with latest status

Fix Dockerfile Python script creation - replace heredoc with echo statements

Fix Python syntax error in word_boundary.int creation - Replace broken inline Python with proper script file - Create create_word_boundary.py with proper indentation and syntax - Add additional silence phone types (SPN, spn) to mapping - Script creates proper Kaldi word boundary format

Fix download_model.sh syntax error and create missing word_boundary.int - Remove broken sed command that corrupted download_model.sh - Generate word_boundary.int from phones.txt during build - Create proper phone boundary mappings for Kaldi - Show word_boundary.int content during build for verification

Pre-extract data.tar.gz during Docker build to fix word_boundary.int issue - Download and extract data files during build instead of runtime - Modify download_model.sh to skip data download if directory exists - Show data directory structure during build for verification - This should resolve the missing word_boundary.int file error

Add comprehensive debugging for UFPAlign data extraction issue - Log directory structure before and after UFPAlign execution - Check for data/lang/phones/word_boundary.int file existence - Identify where data extraction/copying is failing - Debug both source UFPAlign/data and target egs/UFPAlign/s5/data directories

Fix UFPAlign data extraction and environment setup - Add UFPALIGN_DIR environment variable as expected by UFPAlign script - Grant user sudo privileges for file extraction operations - UFPAlign script uses sudo for directory creation and file operations - This should resolve word_boundary.int missing file error

Fix Kaldi egs directory permissions for UFPAlign - Grant user write permissions to /opt/kaldi/egs directory - UFPAlign needs to create working directories in KALDI_ROOT/egs/UFPAlign/s5 - Resolves 'mkdir: Permission denied' error during alignment execution
