Firefox can't use piper?

[AviloLlama]

I cannot use piper voices with read-aloud. Whenever i try to use or test a piper voice using read-aloud i get the error message:

"no availale backend found. ERR: [wasm] RuntimeError: Aborted(CompileError: wasm vailidation error: at offset 23457: element index out of range). Build with -sASSERTIONS for more ingor., [cpu] Error: previous call to 'initWasm()' failed."

Activity Log for piper.ttstool.com is the same:

"Synthesizing 'About Store....' using southern_english_female [low] Error: no available backend found. ERR: [wasm] RuntimeError: Aborted(CompileError: wasm validation error: at offset 23457: element index out of range). Build with -sASSERTIONS for more info., [cpu] Error: previous call to 'initWasm()' failed."

I am using latest firefox release [Version 137.0.2 (64bit)] which supports webassembly.

To be clear, other voices work like the offlilne voices, default, etc. Its just piper that has this issue.

Could you go to this URL on your Firefox and use the Test form to test Piper voices? https://piper.ttstool.com/?test

This will run as a web app completely independent from Read Aloud.
