The invention discloses an answer judgment method based on speech recognition. The method comprises the following steps: acquiring the speech information of user answers; carrying out recognition treatment on the speech information to obtain an answer pinyin sequence; extracting the pinyin information of a keyword from the answer pinyin sequence; splitting the initial consonants and the vowels ofthe pinyin of the keyword; searching a confusion initial consonant and a confusion vowel corresponding to the split initial consonant and the vowel in a stored initial consonant and vowel confusion library according to the split initial consonant and the split vowel; matching and combining the split initial consonant, the split vowel, confused initial consonants and confused vowels again to obtainthe new keyword pinyin information; and respectively matching the pinyin information of the keyword and the pinyin information of a new keyword with the pinyin of a current question answer, and judging whether the user answer is correct or not. Through the pinyin and similar pinyin matching mode, the purpose of automatic loose answering is achieved. The problem that the oral teeth of children arenot clear is solved.
