[google_cloud_texttospeech] Cannot change speaking_rate.

[iory]

text2wave reads speaking_rate at first and sample launch file gives speaking_rate
https://github.com/jsk-ros-pkg/jsk_3rdparty/blob/master/3rdparty/google_cloud_texttospeech/launch/google_cloud_texttospeech.launch#L46 .
However, it seems that this speaking_rate cannot be given correctly.

this line does not have the effect?

Line 10 in 2776781

speaking_rate = rospy.get_param('~speaking_rate', 1.0)

text2wave is not a rosnode. It is called from os.system in sound play node.
Unfortunately, the ros namespace is not carried over to text2wave.

@knorth55 in order to solve this issue, we need to make the tts module as plugin in sound_play.
