To reduce manual testing efforts, we need to design an automation solution that can be used to test these devices in multiple languages.

The easiest approach is to develop automation scripts for such voice-integrated devices.

1. One of the key challenges is how to send commands to the device in different languages.
2. How to capture and interpret the response from the device.
3. How to validate the response against the expected output.

TESTING CONDITIONS

1. To send a command to a device without manual effort, first identify the command in text format and convert it into audio format.
2. Play the audio so that voice-enabled devices can receive and process the command.
3. Wait for the device’s response, record it as an audio file, and finally convert the audio into text to compare it with the expected output.
