Ubuntu 18 speech-d versions

[Linux for blind general discussion]

Okay, simple question.....I run 18.04 Ubuntu completely up to date with 
all updates. Now, two questions....


1. Am I able to install speech-dispatcher git from Github alongside the 
existing speech-dispatcher 0.88 that comes with Ubuntu 18.04?

2. If not, will I be able to simply install the speech-dispatcher git 
and effectively 'replace' the default speech-dispatcher, and have my 
default voices and Orca work without changing anything?


3. If I can have both the default speech-dispatcher and the 
speech-dispatcher git installed, am I able to have Orca use both of them?
