Hiya
Sad to hear.
Maybe this will help a SL T2S client.
Lightweight and tested ( not my code but I did watch it carefully and have a dig) IDOBATA2 - Text chat to speech tool - (kanae.net)
It want to be registered but seems to be ok without.
Also. the best place to get better voices is here. They do 30 day trials - cost e30
Best wishes and fare well
