Testing the sound card

The TwinCAT Speech Configurator allows you to test and identify sound cards from the target system for later use as a microphone for ASR or as a playback device for TTS.
The devices are detected and also identified via the Windows operating system, so the configuration must normally be specific to a target system. An exception to this is the default sound card configured in Windows, which can also be used.
