voice_text

ROS Interface for HOYA VoiceText Speech Synthesis Engine

Installation

1. Install VoiceText SDK

If you have voicetext sdk install binary, please follow the official guide and install both engine and SDK

If you don’t have the sdk install binary but have ReadSpeaker API binary, please follow the guide below.

1. Install VoiceText Engine by official guide
2. Copy VoiceText API binaries to VoiceText binary directory VoiceText API package includes binary libraries and header file. You have to copy those of them to specific directory by executing following commands.

  cd /path_to_api_package_directory # e.g. cd ~/Downloads/RS_VTAPI_SDK_Linux_4.3.0.2/20201113_VTAPI4.3.0.2_LINUX
  cd bin/x64 # You have to cd x86 if your system is x86 architecture
  # Assuming VoiceText engine's talker is hikari, type is D16. If it is different, please set appropriate directory.
  sudo cp -a * /usr/vt/hikari/D16/bin # Don't forget to add -a not to break symbolic link. 
  

2. Put license file

3. Build this package

cd /path/to/catkin_workspace
catkin build voice_text

Usage

1. Launch voice_text node

roslaunch voice_text voice_text.launch

TIPS If you want to launch VoiceText engine on remote machine, try creating launch file like below:

<launch>
  <machine name="remote" address="192.168.0.3" />
  <include file="$(find voice_text)/launch/voice_text.launch">
    <arg name="machine" value="remote" />
  </include>
</launch>

1. Say

Now speech synthesis is enabled.

rosrun sound_play say.py Hello! dummy 1.0 robotsound:=robotsound_jp

Robot says “Hello!”
