The blind test

You will not be told which clip is which until you have answered — that is the whole point. Nothing is recorded about you: the vote is stored against a hash of your browser, so that one person cannot answer a thousand times.

Which one sounds more like a person, rather than a machine reading?

Both clips are the same voice saying the same words. One is the reading engine, one is the expressive engine, and the order is random.

  1. Clip A
    0:00···
  2. Clip B
    0:00···

Play both all the way through before you choose. Answered so far from this browser: 0.

Where it stands

These are self-selected internet listeners, not a controlled panel in a quiet room: read the tally as a signal, not as a MOS score. If you run listening tests properly and want to run one on this catalogue, we will hand over the files.
