Tencent AI Lab deputy Yu Dong was named a 2022 ACM Fellow for his groundbreaking work in speech processing and deep‑learning applications, boasting over 100 patents, multiple best‑paper awards, and technologies now embedded in many of Tencent’s products.
This paper presents an end‑to‑end approach for extracting relational triples directly from speech signals, bypassing intermediate transcription, and demonstrates its effectiveness on synthesized speech versions of the CoNLL04 and TACRED datasets, highlighting challenges such as length constraints and cross‑modal alignment.
This article details the evolution of the voice endpoint detection (VAD) module in 58.com’s voice robot, comparing a dual‑threshold method, Google’s WebRTC VAD, and the deep‑learning based VADNet, and presents experimental results on accuracy, recall, F1 score and online latency.
This article presents 58.com’s intelligent voice quality inspection system, detailing its overall architecture, speech separation, speaker role identification, NLP‑based tagging, model choices such as VGG, BERT, ALBERT and SPTM, and real‑world call‑center use cases that improve efficiency and reduce risk.
This article details the architecture and implementation of the voice call module of an intelligent voice robot, covering SIP signaling establishment, RTP session handling, audio encoding/decoding, sampling, and packetization to enable automated outbound calls and multi‑round voice interactions.
