I imagine the reason why progress on this model has been slow is how very extremely challenging the task is. It would require a sturdy knowledge of linguistics, physics, computer programming, etc. The sampling model in contrast is a piece of cake. The anatomical model does indeed sound very interesting. Each phoneme would be recognized as one particle, on which intonation and dynamics effects could be applied algorithmically; and much of advancement in this area would be employable by speech recognition models, probably increasing their accuracy by a considerable amount. I really hope some serious contenders step up to the plate for this.
