Adversarial Speech-to-Text Examples: a Linguist's View

2018-02-02⊺16:24:18-06:00

A professional linguist examines a recent paper dealing with adversarial examples against speech-to-text systems created by machine-learning techniques. His conclusion is that, for some applications, the existence of adversarial examples won't make any difference, but they show that the speech-to-text systems are “brittle” and hence unsuitable in applications requiring any kind of fine discrimination or nonstandard input.

For many commercial STT and associated user-centric applications this is mostly a curiosity. If I can order pizza and nearly always get it right in one take through Siri, I don't really see the problem here, even if it is obviously highly brittle. …

Nonetheless, I think this brittleness does have consequences. There will be critical uses for which this technology simply can't work. Specialised dictionaries may exist (e.g. clinical terminology) for which it may be almost impossible to obtain sufficient training data to make it useful. Poorly represented minority accents may cause it to fail. Stroke survivors and those with voice or speech impairments may be unable to use them. And there are attacks … in which a device is hacked remotely.
