Method and Apparatus for Converting Voice into Text in Multiparty Call

A method for converting a speech-to-text in a multiparty call, applied to a server, wherein the method comprises:

• receiving speech-to-text requests that are sent by at least two terminals, wherein the speech-to-text requests comprise a first identifier and a second identifier;
• allocating a session to the at least two terminals, so that in the speech-to-text requests sent by the at least two terminals, terminals that have a same first identifier or a same second identifier have a same session;
• receiving, by using a packet-switched domain, a voice stream whose sampling rate is greater than 8 KHz and that is sent by at least one terminal in one multiparty call, wherein the multiparty call corresponds to one session;
• converting the voice stream into a text;
• and
• sending the text to a terminal in the multiparty call.

An apparatus for converting a speech-to-text in a multiparty call, wherein the apparatus comprises:

• a first receiver configured to receive speech-to-text requests that are sent by at least two terminals, wherein the speech-to-text requests comprise a first identifier and a second identifier;
• a processor;
• a memory storing a program to be executed on the processor, the program comprising instructions configured to allocate a session to the at least two terminals, so that in the speech-to-text requests sent by the at least two terminals, terminals that have a same first identifier or a same second identifier have a same session;
• a second receiver configured to receive, by using a packet-switched domain, a voice stream whose sampling rate is greater than 8 KHz and that is sent by at least one terminal in one multiparty call, wherein the multiparty call corresponds to one session;
• the program comprising further instructions configured to convert the voice stream into a text;
• and
• a transmitter configured to send the text to a terminal in the multiparty call.
