UnverifiedWhen there is speaker overlap between the training set and test set, an accent classification model may learn to recognize specific speakers rather than accent features, leading to inflated evaluation results.74% similarUnverifiedThe engineering challenge of voice annotation lies in "hotword recognition," as general-purpose ASR models have lower recognition rates for specialized label vocabulary, requiring hotword lists or few-shot fine-tuning to improve accuracy.74% similarUnverifiedAutomatic speech recognition can still make errors in scenarios involving technical terminology, multiple speakers, and accents, directly affecting retrieval quality.72% similarUnverified传统语音助手基于意图识别与槽位填充技术，只能处理预定义的指令模板72% similarUnverifiedEarly mainstream speech recognition solutions relied on Hidden Markov Models (HMM), which had limited capabilities for noise, accent, and multilingual mixed recognition.71% similar
