Method and device of matching speech input to text

A system, comprising:

• one or more processors;
• and
• memory storing instructions which, when executed by the one or more processors, cause the processors to perform operations comprising:
• storing a list of a user's contacts in the memory, wherein the list of the user's contacts includes a first contact;
• receiving input speech information;
• obtaining initial text corresponding to the input speech information and standard pinyin of the initial text;
• generating at least one approximate pinyin for the initial text based on predetermined pronunciation similarity information, wherein the pronunciation similarity information identifies non-standard pronunciations based on regional dialects;
• from a preset mapping relationship table stored in the memory, obtaining alternative text corresponding to the approximate pinyin of the initial text, wherein:
• the preset mapping relationship table includes a record for each word in a word database, the record including standard pinyin and approximate pinyin for the word, and a mapping relation between the standard pinyin, approximate pinyin, and the word;
• and
• the alternative text includes one or more words whose standard pinyin or approximate pinyin map, in the preset mapping relationship table, to the approximate pinyin of the initial text;
• matching the alternative text to the first contact;
• and
• performing an operation using the first contact.

A non-transitory computer-readable storage medium having storing instructions which, when executed by one or more processors, cause the processors to perform operations comprising:

• storing a list of a user's contacts in the memory, wherein the list of the user's contacts includes a first contact;
• receiving input speech information;
• obtaining initial text corresponding to the input speech information and standard pinyin of the initial text;
• generating at least one approximate pinyin for the initial text based on predetermined pronunciation similarity information, wherein the pronunciation similarity information identifies non-standard pronunciations based on regional dialects;
• from a preset mapping relationship table stored in the memory, obtaining alternative text corresponding to the approximate pinyin of the initial text, wherein:
• the preset mapping relationship table includes a record for each word in a word database, the record including standard pinyin and approximate pinyin for the word, and a mapping relation between the standard pinyin, approximate pinyin, and the word;
• and
• the alternative text includes one or more words whose standard pinyin or approximate pinyin map, in the preset mapping relationship table, to the approximate pinyin of the initial text;
• matching the alternative text to the first contact;
• and
• performing an operation using the first contact.
