To test if the voice connection with the chatbot is working, you can use the Botium Box Live Chat:
Use the Record button at the bottom to record your voice - when doing it for the first time, your browser will ask you for permission to use the microphone.
When you have done your recording, you can listen to it, and then send the audio recording to your chatbot with the Send button.
The chatbot response will be shown in the chat window. Depending on the technology there will be text, audio files, pictures or other content.
