I am just wondering whether nonsense speech testing has ever been extended
to sentences. That is, has anybody ever made an algorithm that
creates nonsense sentences "in a given language". By this restriction I
mean that
1. Some basic statistics of the generated sentences (e.g. phoneme
statistics, word-length statistics) should fit that of the language.
2. The generated sentences should obey the phonotactic rules of the
3. The edit distance between the words of the generated text and any real
word of the language should by larger than a certain threshold.
