    • In one aspect, a method for determining a validity of an identity asserted by a speaker using a voice print is provided. The method comprises acts of performing a first verification stage comprising comparing a first voice signal from the speaker uttering at least one first challenge utterance-with at least a portion of the voice print and performing a second verification stage if it is concluded in the first verification stage that the first voice signal was obtained from an utterance by the user. The second verification stage comprises adapting at least one parameter of the voice print based, at least in part, on the first voice signal to obtain an adapted voice print, and comparing a second voice signal from the speaker uttering at least one second challenge utterance with at least a portion of the adapted voice print.
    • 在一方面,提供了一种用于确定由使用语音打印的扬声器所确定的身份的有效性的方法。 该方法包括执行第一验证阶段的动作,包括将来自扬声器的第一语音信号与至少一个第一挑战话语 - 与语音打印的至少一部分进行比较,并且如果在第一验证中得出结论,则执行第二验证阶段 第一语音信号是由用户的话语获得的。 第二验证阶段包括至少部分地基于第一语音信号来调整语音印刷的至少一个参数以获得适应的语音印刷,并且将来自扬声器的第二语音信号与至少一个第二挑战话语与 至少一部分适应的语音打印。

    • In one aspect, a method for determining validity of an identity asserted by a speaker using a voice print associated with a user whose identity the speaker is asserting, the voice print obtained from characteristic features of at least one first voice signal obtained from the user uttering at least one enrollment utterance including at least one enrollment word is provided. The method comprises acts of obtaining a second voice signal of the speaker uttering at least one challenge utterance, wherein the at least one challenge utterance includes at least one word that was not in the at least one enrollment utterance, obtaining at least one characteristic feature from the second voice signal, comparing the at least one characteristic feature with at least a portion of the voice print to determine a similarity between the at least one characteristic feature and the at least a portion of the voice print, and determining whether the speaker is the user based, at least in part, on the similarity between the at least one characteristic feature and the at least a portion of the voice print.
