The invention relates to the technical field of intelligent
contact center outbound voice
processing, and discloses a low-
delay streaming ICC outbound
large model voice-to-text method, which comprises the following steps: capturing a bidirectional RTP voice
stream through a FreeSWITCH
media server, marking according to a Call-ID, analyzing SDP media parameters by a
Java control center, associating the SDP media parameters with the Call-ID, and pushing the SDP media parameters to an ASR service; after the ASR service
decodes the audio and preprocesses the audio, the audio is submitted to the FUNASR engine in a streaming mode to obtain a transcription text; and executing semantic correction through a large
language model, outputting a
structured text, asynchronously distributing the
structured text to real-time quality inspection and intelligent auxiliary service through a
message queue, and finally pushing a result to a seat
workbench in real time. According to the method, voice
stream-signaling
collaboration, low-
delay transcription and semantic precision optimization are realized, real-time quality inspection and intelligent assistance of outbound calling are supported, and the
service quality and conversion efficiency are improved.
