摘要： A method and system for automatically generating a scoring model for scoring a speech sample are disclosed. One or more training speech samples are received in response to a prompt. One or more speech features are determined for each of the training speech samples. A scoring model is then generated based on the speech features. At least one of the training speech samples may be a high entropy speech sample. An evaluation speech sample is received and a score is assigned to the evaluation speech sample using the scoring model. The evaluation speech sample may be a high entropy speech sample.

摘要： A method and system for providing immediate diagnostic feedback on speech samples of non-native speakers are disclosed. A scoring model is generated based on speech features extracted from one or more training speech samples. An evaluation speech sample is received and speech features of the evaluation speech sample are determined. Based on the scoring model and the speech features, diagnostic feedback is provided to the speaker. In an alternate embodiment, speech features are extracted from an evaluation speech sample. The speech features are then compared with optimal values, ranges of values, or norms for those features. Based on the result of the comparison, diagnostic feedback is provided to the speaker.

摘要： Systems and methods are provided for scoring non-native speech. Two or more speech samples are received, where each of the samples are of speech spoken by a non-native speaker, and where each of the samples are spoken in response to distinct prompts. The two or more samples are concatenated to generate a concatenated response for the non-native speaker, where the concatenated response is based on the two or more speech samples that were elicited using the distinct prompts. A concatenated speech proficiency metric is computed based on the concatenated response, and the concatenated speech proficiency metric is provided to a scoring model, where the scoring model generates a speaking score based on the concatenated speech metric.

摘要： The present disclosure presents a useful metric for assessing the relative difficulty which non-native speakers face in pronouncing a given utterance and a method and systems for using such a metric in the evaluation and assessment of the utterances of non-native speakers. In an embodiment, the metric may be based on both known sources of difficulty for language learners and a corpus-based measure of cross-language sound differences. The method may be applied to speakers who primarily speak a first language speaking utterances in any non-native second language.

摘要： A method for scoring non-native speech includes receiving a speech sample spoken by a non-native speaker and performing automatic speech recognition and metric extraction on the speech sample to generate a transcript of the speech sample and a speech metric associated with the speech sample. The method further includes determining whether the speech sample is scorable or non-scorable based upon the transcript and speech metric, where the determination is based on an audio quality of the speech sample, an amount of speech of the speech sample, a degree to which the speech sample is off-topic, whether the speech sample includes speech from an incorrect language, or whether the speech sample includes plagiarized material. When the sample is determined to be non-scorable, an indication of non-scorability is associated with the speech sample. When the sample is determined to be scorable, the sample is provided to a scoring model for scoring.
摘要翻译：用于对非本机语音进行评分的方法包括接收由非本地语音讲话者所说出的语音样本，并在语音样本上执行自动语音识别和度量提取，以产生语音样本的抄本和与语音样本相关联的语音度量。该方法还包括基于抄本和语音度量确定语音样本是可划分的还是不可读的，其中确定是基于语音样本的音频质量，语音样本的语音量，语音样本是脱离主题的，语音样本是否包含来自不正确语言的语音，或者言语样本是否包括剽窃材料。当样本被确定为不可扫描时，不合格性的指示与语音样本相关联。当样品被确定为可扫描时，将样品提供给评分模型进行评分。
