Audio and speech packages

The Audio and Speech accessory package provides audio input and output hardware as well as development libraries for speech recognition and speech synthesis (text-to-speech).

The audio package for Pioneer and PeopleBot includes a pair of miniature microphones (combined to one channel) which are normally attached to the top of the upper deck of the Peoplebot or above the laser bracket or speaker brackets of a Pioneer, but which may be relocated as needed.  The Peoplebot includes stereo speakers integrated into the robot (near the top of each strut which supports the upper deck).  On the Pioneer, the speakers are externally mounted on the top deck of the robot (the speakers are attached by a thumb screw which allows a few degrees of rotation of the speakers, and also allows them to be easily removed for repositioning or use without speakers.)  Amplifier is included with each.

The audio package for PatrolBot includes an active noise canceling microphone in an enclosure with “recording” indicator light (on top deck), and speakers integrated into the robot interior (under deck), as well as amplifier.

Both packages include software development libraries for performing speech recognition and speech synthesis via the Cepstral speech synthesis engine (two voices included).

ARIA includes tools for playing sounds (WAV files) on either Linux or Windows, as well as a tool for managing sequential output of multiple sounds or recurring sound and speech output events.
