19. The speech translation method of claim 11 , wherein the segment boundary for the first-language translatable segment is determined based on at least one additional indicator.
11. A speech translation method for translating speech, comprising: accepting, by a first-language automatic speech recognition unit, spoken sound from a first speaker in a first language and creating a plurality of partial hypotheses of the spoken sound of the first speaker in substantially real time while the first speaker is speaking; merging, by a first-language resegmentation unit that is in communication with the first-language automatic speech recognition unit, at least two of the partial hypotheses received from the first-language automatic speech recognition unit; resegmenting, by the first-language resegmentation unit, the merged partial hypotheses into a first-language translatable segment in the first language, wherein a segment boundary for the first-language translatable segment is determined based on sound from a second speaker in a second language; and outputting, by a first-language machine translation unit that is in communication with the first-language resegmentation unit and that receives the first-language translatable segment in the first-language from the first-language resegmentation unit, a translation of the spoken sound from the first speaker into the second language based on the received first-language translatable segment.
