Audio Study

Welcome to Nina's Audio-Rating Study

The task takes approximately 15 minutes to complete. Participants will listen to speech samples and rate the perceived audio quality.

The study includes ten minimal word pairs. Each pair consists of the same word with one phoneme (speech sound) changed, resulting in a different meaning.

Instructions:

Please listen carefully to all audio files (circular play buttons).
For each item, move the slider to provide your rating.
Once all required responses on a slide are completed, the questions will be marked with a green background.
Please make sure to move each slider at least once, as responses are only recorded after the slider has been adjusted.
You can proceed to the next slide only after all items are marked green.
Ideally, please use headphones to ensure you can hear subtle audio differences clearly.

Your participation is a great help and is highly appreciated.

Thank you very much for supporting my research!
