res_speech: allow speech to translate input channel

Browse Source 
* Allow res_speech to translate the input channel if the
  format is translatable to a format suppored by the
  speech provider.

Resolves: #129

UserNote: res_speech now supports translation of an input channel
to a format supported by the speech provider, provided a translation
path is available between the source format and provider capabilites.
