I'm assuming the defaults here. My serial ports are also not using any nonstandard port addresses or IRQ assignments. After the make appears to go well, launching EmacSpeak as described starts Emacs, but I still do not receive any speech from the DecTalk. It is very difficult for me to dig around in what is going on as I currently lack any speech access to this system and must obtain help from nontechy sighted people. I hope that this is something common that can be semi-easily fixed.
Any help is appreciated.
