Email reader for RISC OS operating system.
...From v3.16 onwards the RISC OS version of eSpeak is not included in the Pluto download, but separately in the Files espeak directory. The espeak project itself is on https://espeak.sourceforge.net/ but seems currently dormant.
For full details of all updates since v3.06b, please see the Pluto Web Site on http://www.avisoft.f9.co.uk/pluto/
