For example, the specific template of the short-text message relevant with the meeting request may be as follows: " Meet me at$PLACE At$TIME. ".In this sentence, fixedly language element is marked by underscore, and variable language element is then capitalized and started with " $ ".So, the different user of template just can be edited variablees such as Zhu Ru $PLACE to adapt to its particular environment.For example, the university student may be set at: $PLACE=sp|library (library) to variable De $PLACE | dormitory (dormitory) | and cafeteria (cafeteria) or the like and the lawyer may be set at: $PLACE=sp|office (office) to variable De $PLACE | courthouse (law court) | home (family) or the like
In the superincumbent sentence, " sp " refers to pause or do not have speech, and " | " refers to logical operator " OR ".
Another example of the source template that may use is in the present invention: " Happy$FESTIVAL. ".Variable Yu Yanchengfen $FESTIVAL in this sentence may be compiled by the user:
$FESTIVAL=sp|birthday (birthday) | new year (New Year) | thanksgiving (Thanksgiving Day) or the like
By using open vocabulary speech recognition, phone 100 can identify the variable language element of having edited by user's input.Because variable language element is made up of the discrete set of variable, the expense and the memory requirements of voice recognition processing are reduced to minimum.Therefore said method is specially adapted to only have the limited processing and the equipment of memory source, such as mobile phone.
The use of the template that comprises fixing and variable language element has been improved the efficient of speech recognition system aspect several.One, because the quantity of the template of storage is few with respect to the almost unlimited quantity of arranging with the sentence of natural language sentences structurally associated connection in static programmable memory 155, so can identify the fixedly language element in the specific template fast and effectively usually.Its two since source template in variable language element the sentence in the position can automatically identify the discrete set that may answer language, so also can identify variable language element efficiently.For example, with above-mentioned " Happy$FESTIVAL " source template is example, fixedly language element " Happy" can be used as a signal, processor 110 is known: the speech input subsequently that microphone 190 receives will be variable language element “ $FESTIVAL ".
Though the above embodiment of the present invention illustrates that by wireless telephone 100 other electronic equipment of the provided text message such as personal digital assistant (PDA) also can be provided method and apparatus of the present invention.
Therefore, the present invention has simplified from portable electric appts provides and sends the required step of text message.Text message can provide by speech input rather than from the mode of miniature keyboard typing character.In addition, the present invention can comprise open vocabulary speech recognition, with the closed vocabulary speech recognition of the avoiding prior art height requirement to internal memory.Sub-speech (sub-word) acoustic model that is independent of loudspeaker is adopted in open vocabulary speech recognition, is designed to contain a kind of all sound phenomenons (occurrence) or phoneme (phoneme) of language.Therefore, the user is not limited to and only uses predefined vocabulary, also can edit aforesaid variable language element, to comprise the word that can not find out such as in the dictionaries such as name and place name.Therefore text message provided by the invention can be personalized to heavens.
Above-mentioned detailed description only provides preferred one exemplary embodiment, and does not regard the restriction to scope of the present invention, applicability or configuration as.Say that more suitably the detailed description of this preferred one exemplary embodiment provides the guidance note that realizes preferred one exemplary embodiment of the present invention to those of ordinary skill in the art.Should be appreciated that under the prerequisite that does not deviate from desired the spirit and scope of the present invention in the claims, can make multiple change the function and the arrangement of assembly.
