How to use the Bing Speech Recognition robot skill
This speech recognition skill for ARC uses the Bing Speech Recognition cloud service. It is one of the most accurate speech recognition services available.
Two Version Of This Skill
There are two version of this robot skill, this one and the Advanced Speech Recognition. This version of the robot skill uses a shared license key with Microsoft that enables ARC users to experiment and demo this robot skill. Because this version of the skill shares a license key, users may encounter errors if more than one ARC instance uses this skill. For serious testing and development, we recommend setting up your key with Microsoft by using the Advanced Speech Recognition instead.
Most robots make a lot of noise, so locating the audio input device on a robot is not a practical solution. It is best to find the microphone on the controlling PC/Laptop, on yourself, or somewhere in the room (away from the robot). Turning the gain higher on the input device will allow voices to be recognized across large rooms and increase false positives. Test with different gains for the best resolution. Experiment with varying locations of the microphone and volumes for the best setup for your environment. Ideally, use a headset or Bluetooth mic rather than your laptop microphone.
1. Start Recording Button
This button starts the Bing Speech Recognition; it will detect silence until you speak, then detect the words you are saying and display them in the Response Display.
2. Audio Waveform
This gives visual feedback that your audio input device (microphone) is configured correctly and is picking up voice/sounds.
3. Response Display
Here you will get speech recognition feedback. It will show the text version of your detected words or silence.
1. Phrase List
This is a list of default phrases with the ability to customize and add more phrases.
2. Command List
This is a list of default commands corresponding to the phrases in the same row, with the ability to customize and add more commands.
3. All Recognized Script
This script will execute for every detected phrase. If there is no match for recognition, this script will still be executed, but the variable will be empty. You can tell if no speech was spoken because the variable will be empty, and this script will be executed.
4. Variable Field
This variable holds the text from the speech recognizer. This may be used in your script to determine what was spoken. If the variable is empty, no speech was recognized (i.e., silence).
5. Auto Record Checkbox
If this checkbox is enabled, the skill will begin recording audio when it has been detected. The threshold is adjusted in the Level Threshold setting.
6. Level Threshold Field
This adjustable threshold level is used for Auto Recording (if enabled) and stopping recording. If you find that even in manual mode, the recording manually stops too quickly before your sentence is complete, lower this value.
7. Silence Count Field
This count sets how often the energy volume is below the threshold before recording is stopped.
8. Max Recording Field
This represents the maximum duration of the recording. *Note: Currently locked to 10 seconds.
9. Strip Punctuation Checkbox
If this checkbox is enabled, punctuation will be stripped from the detected recording when displaying it on the Response Display. This is helpful when you're looking to detect certain words or phrases.
10. Setup Microphone Button
This button is a shortcut to the properties of your installed audio input devices. Verify that your device is working by watching the soundbar for movement when you speak into that device.
11. List Management Buttons
These buttons manage the rows of phrases. They move the rows up and down, insert them, add more to the bottom, and delete them.
12. Language Drop-down
ARC uses the Microsoft Speech Recognition included with Windows. All languages supported by Windows Speech Recognition are also supported in ARC. You can configure Windows to listen to any language. ARC will default to EN-US (English) language if installed. Otherwise, ARC will default to the first installed language. If more than one language is installed, a language may be selected with this drop-down.
*Note 2: Languages supported by speech recognition depend on the Microsoft Windows operating system configuration. View the Microsoft speech recognition guide here to view supported languages.
13. Not Handled Script
This script will execute for every detected phrase not in the phrase list. This script will not be called if there is a match from the phrase list.
How to Use Bing Speech Recongition
A detailed tutorial provides an example of using this robot skill in conjunction with PandoraBot AI to have a conversation with your robot. You can find the tutorial by clicking here.
Control commands will send instructions from one robot skill to another. Read more about the ARC control command feature by clicking here.
ControlCommand("PandoraBot", SetPhrase, $BingSpeech)
When this skill detects a phrase, it will be assigned to the variable, and the specified script will execute. With this model, you can have this skill send the detected speech to a PandoraBot skill using ControlCommand().
Controls the state of the PAUSE checkbox, which pauses the listening for VAD auto recording. If VAD is disabled, the PAUSE checkbox does not exist. The pause checkbox prevents the VAD from automatically starting recording.
Presses the Start button, which begins listening to audio through the microphone to convert from speech to text. Sending this control command is the same behavior as pressing the Start button.
Presses the Stop button, which stops recording audio that will be converted from speech to text. The Stop button is only visible when the recording is active. Recording can be activated by pressing the Start button or auto-recording when VAD is enabled.
Here's an example of the skill in action combined with the Cognitive Vision and Cognitive Emotion services.
This service requires an internet connection, meaning a second USB WiFi adapter or an ethernet connection may be needed. Read about having 2 network connections here.
Headset or External Mic
A headset or external mic will produce dramatically better results than the internal PC/Laptop mic. A headset or mic will enable the recognition engine to "hear" your voice much clearer with less background noise. The background noise of the laptop, motors, radio, and room echo will cause the recognition software to return False Positives. This means the software recognizes an incorrect phrase. An external mic will also prevent the recognition software from hearing the robot speak. In short, it is important to use a Mic Headset or external Mic for a positive Speech Recognition experience.
Configure Audio Input Device
You might have to adjust the microphone input volume/gain. To change the mic volume, use the Microsoft Windows volume mixer, and first, make sure you have selected the correct input device. Your laptop or computer may have a few different mic devices. Maybe one is on a remote camera. Find the mic you'd like to use and adjust the volume. To find the volume settings that are ideal on your computer, follow these steps:
1) Right-click on the little speaker on your system tray
2) Select "Open Sound Settings."
3) In the "Input" section of the Sound Settings, you'll notice a little VU meter beside the active device. Make sure your active device is indeed the microphone you want to use. By making sounds, the VU meter should move.
4) Click on the "Device Properties" and locate the volume slider for the microphone. We usually have our volume set for 78. Play around with different volumes until you see your voice being picked up by the VU meter. Adjust the volume input level/gain to display your voice's regular volume near the middle of the VU Display graph. If the level/gain is too high, the recognition software will not work because the input audio will be distorted.
You may train your computer for speech recognition by using the training wizard. Find the training wizard under Speech Recognition within the Windows Control Panel.

Anyone Having Issues With Bing Speech Recognition?
Use Voice Recognition For Unsupported Languages
What Is The Difference Between "Pauselistening" And...
Upgrade to ARC Pro
Synthiam ARC Pro is a cool new tool that will help unleash your creativity with programming robots in just seconds!
Error in response received: Server did not recognize the value of HTTP Header SOAPAction: http://tempuri.org/BingSpeechRecognition.
Can anyone help?
I having it speak out of the PC
in the Bing speech I put ControlCommand("PandoraBot", SetPhrase, $BingSpeech)
I use AIMLbot so I can write my own responses
for AIML bot it is about the same:
Bing speech - ControlCommand("AimlBot", SetPhrase, $BingSpeech)
AimlBot - Audio.say(getVar("$BotResponse"));
screen. It looks like the original voice recognition skill.
The new question is if I set my Bing speech to send messages to aimlbot, how can i use bing to do other things like send messages to congnitive vision or servos? It now responds both from the aimbot and the "phrase" and "command".
you’ll find labels and question marks next to options. This applies to all options across the entire ARC software
Have you ever seen this intermittent error:
Error in response received: There was an error during asynchronous processing. Unique state object is required for multiple asynchronous simultaneous operations to be outstanding.
Error in response received: The underlying connection was closed: An unexpected error occurred on a receive.
How you know is you get a message that says the quota is done.
Can anyone else check to see if it's working? Maybe its maintenance on the server?
Edit: now working...go figure!
Server was unable to process request. ---> A task may only be disposed if it is in a completion state (RanToCompletion, Faulted or Canceled).
Is there any way to directly set up Bing Speech Recognition to use a wake word?
And then have the bing speech recognition re-pause itself after it detects a phrase?
Use the Control Command, here's a manual on how to use the ControlCommand and access available commands for each robot skill: https://synthiam.com/Support/Programming/control-command
Essentially, you can right-click in the editor or press the Cheat Sheet tab
PS, the question had been moved from Will's unrelated thread about his youtube channel to here.
I also set a set of lights to flash for the amount of time Bing was listening. That way I know that Bing is actively listening and for how long. That really helped.
Bing is normally paused and wont listen till the script in the Speech Recognition robot skill starts it or you push it's Start Recording button..
Simply add the Speech Recognition robot skill to your project. Make sure it's working and listening.
Add this Ez code and modify it to work with your project.
TIP: If you get false startups of this control just increase the Continence level until it hears the wake word and nothing else. Use a wake word that is not common or is not used too much around the robot.
Nothing else should be in the Speech Recognition robot skill except this wake word.
Works just like Alexa!
If i turn off VAD i do not get the issue. But then have to press stop recording button which defeats the purpose.
Can anyone repeat this issue? Just about to give up on this and move on to another skill.
That way, you're in charge of the key do not need to depend on sharing keys with other users.
When trying to add Bing Speech Recognition I'm getting this error message. Please help, thanks in advance.

I have no trouble having the phrase recognized by Bing. Example: "Look up"
But the action associated with the phrase "Look up" (in the configuration) isn't executed. The characters exactly match but it seems like the phrase isn't detected.
I've even tried removing my "All recognized script" and "Script for not handled" but that didn't help.
I had cut and pasted everything into the phrase list, line by line. I just figured out how it happened. I was cutting and pasting text that was at the beginning of a line of text. When you use cut & paste like that you can inadvertently grab the spaces between words because you are removing all the text.
That's my bad, something to keep in mind for the future.
I wanted to use a different wake word with Bing, so I set it to "Simone." The problem is that when I save the changes, the wake word is not saved. What am I doing wrong?
