Higher values mean that it will be less sensitive, which is useful if you are in a loud room. This value depends entirely on your microphone or audio data. There is no one-size-fits-all value, but good values typically range from 50 to Also, check on your microphone volume settings. If it is too sensitive, the microphone may be picking up a lot of ambient noise. If it is too insensitive, the microphone may be rejecting speech as just noise. Before it is at a good level, the energy threshold is so high that speech is just considered ambient noise.
This causes the default microphone used by PyAudio to simply block when we try to read it. In Python 3, all strings are unicode strings. To make printing of unicode strings work in Python 2 as well, replace all print statements in your code of the following form:.
As of PyInstaller version 3. You can easily do this by running pip install --upgrade pyinstaller. There does not seem to be a simple way to disable these messages. First, ensure you have Homebrew, then run brew install flac to install the necessary files. Version tags are then created using git config gpg. Releases are done by running make-release. Testing is also done automatically by TravisCI, upon every push.
The included flac-win32 executable is the official FLAC 1. The built FLAC executables should be bit-for-bit reproducible. To rebuild them, run the following inside the project directory on a Debian-like system:. The included flac-mac executable is extracted from xACT 2. Specifically, it is a copy of xACT 2.

The settings that can be configured on the Speech Recognition tab include the following:. If multiple engines are installed, you can use the drop down arrow under the Language section to select which one to use. Some engines will also support special features.
If the Settings button is not available, it simply means that the engine selected does not support any custom features. Windows XP stores recognition profiles. The information stored within a profile is used to recognize your voice. You can create different profiles for different users or for different noise environments. To change speech recognition profile setting options, use the steps listed below:.
Under the Recognition Profiles section, you will also see an addition button called Train Profile. This allows you to train your profile to improve speech recognition accuracy. The more the speech engine knows about your particular style of speaking and the sounds in your environment, the more accurate it will be. The wizard will collect voice samples from you so that it can adjust to your particular speaking style.
Finally, at the bottom of the Speech Recognition tab, you can configure microphone settings. Keep in mind that speech recognition performance is dependent on the type of microphone you are using and different microphones will have specific requirements. The Microphone Wizard will appear once you click the Configure Microphone button.
The wizard will walk you through the process of configuring and testing your microphone for use with speech recognition. Assuming that you have completed all the tasks described above, you are almost ready to start using speech recognition in Windows XP. On the Languages tab, click the Details button.
The Text Services and Input Languages dialog box will appear. Under Installed services, select Speech Recognition and click the Properties button. The Speech input settings dialog box will appear as shown in Figure D. Click OK after you have configured the Advanced settings. The Language Bar button is used to configure how you want the Language Bar to appear.
The available options include the following:. The runtime can be downloaded at Microsoft Speech Runtime. The Microsoft Speech Platform relies on different language packs in order to provide speech recognition capabilities for different languages.
Microsoft Speech Platform supports 18 different languages and accents. You can download some of the more popular languages using the links below. For additional options, please contact Inventive Labs Technical Support. All of this functionality is built into Voice Elements. You will not need to have this installed, unless you would like to use it to create Microsoft Compatible Grammar files. After completing the steps above you can enable speech recognition before using the Play and PlayTTS methods by setting SpeechRecognitionEnabled to true before calling them.
For information on how to use the speech recognition demo application for testing, see Test Speech Recognition with Voice Elements. Please note that SpeechRecognitionNumberOfPorts should be set to a number that is equal to or less than the number of Speech Recognition Ports for which you are licensed.
