Linux. I'm trying to add speech synthesis through Piper (which has much better voices than what's installed by default). I've got it set up in speech dispatcher and can use "spd-say" on the command line without issue. But Firefox refuses to say anything through this configuration. I've configured one voice for Piper and it shows up in the voices list in FF. FF can play other sounds just fine, such as video. FF could also play the voices from the other module that was preinstalled. So this might not be a FF issue? But as mentioned, speech dispatcher responds correctly on the command line and FF lists the voice I've configured through it. I'm not sure where to go from here as searching has turned up a lot of dead ends. Any help would be appreciated!
