摘要： A method of recognizing a speaker of an utterance (602) in a speech recognition system, comprising
- comparing the utterance (602) to a plurality of speaker models (604) for different speakers;
- determining a likelihood score (606) for each speaker model, the likelihood score (606) indicating how well the speaker model corresponds to the utterance; and
- for each speaker model (604), determining a probability (609) that the utterance (602) originates from the speaker corresponding to the speaker model (604),
wherein the determination of the probability (609) for a speaker model (604) is based on the likelihood scores (606) for the speaker models and takes a prior knowledge (607) about the speaker model into account.摘要翻译： 一种在语音识别系统中识别说话者的方法（602），包括：将所述话语（602）与不同说话者的多个说话者模型（604）进行比较; - 确定每个说话者模型的可能性得分（606），所述可能性得分（606）指示说话者模型对应于话语的程度; 以及 - 对于每个说话者模型（604），确定所述话语（602）源自与所述说话者模型（604）相对应的说话者的概率（609），其中，确定所述说话者模型（604）的概率（609） ）基于说话者模型的可能性得分（606），并且考虑到关于说话者模型的先验知识（607）。

摘要： The invention is directed to a method for determining barge-in in a speech dialog system comprising determining whether a speech prompt is output by the speech dialog system, detecting whether speech activity is present in an input signal based on a time-varying sensitivity threshold and/or based on speaker information, wherein the sensitivity threshold is increased if output of a speech prompt is determined and decreased if no output of a speech prompt is determined.

摘要： This invention provides a method for determining, in a speech dialogue system issuing speech prompts, a score value as an indicator for the presence of a wanted signal component in an input signal stemming from a microphone, comprising the steps of: using a first likelihood function to determine a first likelihood value for the presence of the wanted signal component in the input signal, using a second likelihood function to determine a second likelihood value for the presence of a noise signal component in the input signal, and determining a score value based on the first and the second likelihood values, wherein the first likelihood function is based on a predetermined reference wanted signal, and the second likelihood function is based on a predetermined reference noise signal.
