identifying a plurality of silent sections in the audio input;
obtaining a type input indicating a type of the speech data in the audio input, wherein the type input indicates that the speech data is a customer service call, a public speech, or a lecture;

grouping the plurality of silent sections into the plurality of groups, wherein each group in the plurality of groups corresponds to a punctuation mark or a space without a punctuation mark, wherein the grouping the plurality of silent sections into the plurality of groups is done at least partially by using the expected distribution; and
associating each silent section in the plurality of silent sections with a punctuation mark or a space according to the group of the silent section, thus obtaining punctuation information,
performing a speech-to-text conversion on the audio input, thus obtaining a transcript of the speech data; and
