How is possible to add new speechT5 models

[virtualrobotix]

How is possible change the text to speech model ? Is possible to use other .bin like voxpopuli for Italian language or other trained by ourself ? I try to add the voxpopuli.bin file in the public directory but the app stop to work without info in debug . The main difference is that original model are 2 kbyte the voxpopuli are 500 mbyte .
