    摘要： The invention relates to a method of automatic recognition of an at least partly spelled speech utterance, with a speech recognition unit (2) based on statistical models that include a linguistic speech model (6). To improve this method in such a way that in addition to a convenient entry, also a reduced speech recognition error rate is achieved, there is proposed that after the at least partly spelled speech utterance has been entered, the speech recognition unit (2) determines a first recognition result for the whole speech utterance; individually recognized letters are sent to the user for him to acknowledge or reject; after a letter has been acknowledged, the linguistic speech model (6) is adapted, which linguistic speech model, after its adaptation, determines the number of letters that can be allowed as followers of the acknowledged letters and assumes the correctness of letters already acknowledged; the speech recognition unit (2) determines a further recognition result for the speech utterance by means of the adapted linguistic speech model (6), from which result the next letter to be sent to the user is determined, so that he can acknowledge it.

    摘要： Some embodiments provide retail product ordering systems comprising: a user computing device comprising an application executed by a device control circuit to: receive an audible utterance; controls a product identifier application interface to: apply a tokenizer model and obtain a set of individual search words; apply a series of featurizer models to the search words to generate features; and apply a classifier and extractor model based on the features and generate multiple requested product entities each comprising a respective sub-set of the position labeled product terms; wherein the device control circuit is further configured to access a purchase history database, confirm an accuracy of each of requested product entities relative to a purchase history, generate a listing of determined product identifiers corresponding to the confirmed set of the multiple requested product entities, and control a display system of the user computing device to render the listing of determined product identifiers.
