 * Greetings!
 * The Guzzle Library version that Google Text-to-Speech is using must match the
   version of the Guzzle library your plugins because in waterway it is causing 
   this conflict of the Guzzle versions.

 * Hi!
    If you turned off all plugins AND commented out the lines it won’t work.
   Commenting on lines of code is necessary in order for the Speaker to use the 
   Guzzle loaded from the dependencies of another plugin, so if all other plugins
   are disabled the Speaker will not be able to get the Guzzle. In addition, the
   plugin that calls the Guzzle version conflict must use a version no lower than
   5. For information, the Speaker now uses version 7.1.
