+## ReSpeaker Microphone Array
+
+For this tutorial, we will go over on a high level how to use Stretch's [ReSpeaker Mic Array v2.0](https://wiki.seeedstudio.com/ReSpeaker_Mic_Array_v2.0/).
+
+
+
+
+ 
+
+
+
+### Stretch Body Package
+In this tutorial's section we will use command line tools in the [Stretch_Body](https://github.com/hello-robot/stretch_body) package, a low level Python API for Stretch's hardware, to directly interact with the ReSpeaker.
+
+Begin by typing the following command in a new terminal.
+
+```bash
+stretch_respeaker_test.py
+```
+
+The following will be displayed in your terminal
+```bash
+hello-robot@stretch-re1-1005:~$ stretch_respeaker_test.py
+For use with S T R E T C H (TM) RESEARCH EDITION from Hello Robot Inc.
+
+
+* waiting for audio...
+* recording 3 seconds
+* done
+* playing audio
+* done
+
+```
+
+The ReSpeaker Mico Array will wait until it hears audio loud enough to trigger its recording feature. Stretch will record audio for 3 seconds and then replay it through its speakers. This command line is a good method to see if the hardware is working correctly.
+
+To stop the python script, type **Ctrl** + **c** in the terminal.
+
+### ReSpeaker_ROS Package
+
+A [ROS package for the ReSpeaker](https://index.ros.org/p/respeaker_ros/#melodic) is utilized for this tutorial's section.
+
+Begin by running the `sample_respeaker.launch` file in a terminal.
+
+```bash
+# Terminal 1
+roslaunch respeaker_ros sample_respeaker.launch
+```
+This will bring up the necessary nodes that will allow the ReSpeaker to implement a voice and sound interface with the robot.
+
+Below are executables you can run and see the ReSpeaker results.
+
+```bash
+rostopic echo /sound_direction # Result of Direction (in Radians) of Audio
+rostopic echo /sound_localization # Result of Direction as Pose (Quaternion values)
+rostopic echo /is_speeching # Result of Voice Activity Detector
+rostopic echo /audio # Raw audio data
+rostopic echo /speech_audio # Raw audio data when there is speech
+rostopic echo /speech_to_text # Voice recognition
+```
+
+An example is when you run the `speech_to_text` executable and speak near the microphone array. In this instance, "hello robot" was said.
+
+```bash
+# Terminal 2
+hello-robot@stretch-re1-1005:~$ rostopic echo /speech_to_text
+transcript:
+ - hello robot
+confidence: []
+---
+```
+
+You can also set various parameters via`dynamic_reconfigure` running the following command in a new terminal.
+
+```bash
+# Terminal 3
+rosrun rqt_reconfigure rqt_reconfigure
+```
