A speech recognition method and an electronic apparatus are provided. The speech recognition method includes the following steps. A plurality of phonetic transcriptions of a speech signal is obtained according to an acoustic model. A phonetic spelling and intonation information matched to the phonetic transcriptions are obtained according to a phonetic transcription sequence and a syllable acoustic lexicon of the invention. According to the phonetic spellings and the intonation information, a plurality of phonetic spelling sequences and a plurality of phonetic spelling sequence probabilities are obtained from a language model. The phonetic spelling sequence corresponding to a largest one among the phonetic spelling sequence probabilities is selected as a recognition result of the speech signal.
