3.4 Changelog

3.4.0

• Compatibility with Kalpy 0.9.0

• Introduced new command for Comparing and evaluating alignments (mfa compare_alignments)

• Introduced new MFA model format for distribution on HuggingFace

• Introduced new commands that use the new MFA model format (i.e. Align with a model hosted on Hugging Face (mfa align_hf)) which will replace the default commands (i.e. Align with an acoustic model (mfa align)) in MFA 4.0. The default commands will still be available using a legacy command and will be removed in MFA 5.0.

• Added calculation for Intensity deviation and Signal-to-Noise Ratio (SNR) to be included as diagnostic metrics for alignment

• Updated calculation for phone duration deviation to use log-duration to better model the duration distribution

• Added column for Max running short intervals as a measure of alignment quality
