Abstract: A system for automated adaptation and improvement of speaker authentication in a voice biometric system environment, comprising a speech sample collector, a target selector, a voice analyzer, a voice data modifier, and a call flow creator. The speech sample collector retrieves speech samples from a database of enrolled participants in a speaker authentication system. The target selector selects target users that will be used to test the speaker authentication system. The voice analyzer extracts a speech component data set from each of the speech samples. The call flow creator creates a plurality of call flows for testing the speaker authentication system, each call flow being either an impostor call flow or a legitimate call flow. The call flows created by the call flow creator are used to test the speaker authentication system.

Abstract translation: 一种用于在语音生物测定系统环境中自动适应和改进扬声器认证的系统，包括语音采样收集器，目标选择器，语音分析器，语音数据修改器和呼叫流创建器。 语音采样收集器从扬声器认证系统中的注册参与者的数据库检索语音样本。 目标选择器选择将用于测试扬声器认证系统的目标用户。 语音分析器从每个语音样本中提取语音分量数据集。 呼叫流创建者产生用于测试说话人认证系统的多个呼叫流程，每个呼叫流程是冒名顶替者呼叫流程或合法呼叫流程。 由呼叫流创建者创建的呼叫流用于测试扬声器认证系统。
