INT2 sponsors VLSP 2022

The 9th International Workshop on Vietnamese Language and Speech Processing (VLSP 2022) is an annual workshop held by the Association for Vietnamese Speech and Language Processing (VLSP), a member of the Vietnam Association for Information Processing (VAIP).

This year, the workshop was hosted by the Vietnam Institute for Advanced Study in Mathematics (VIASM), Ha Noi, on November 26, 2022, with many attractive shared tasks.

VLSP 2022 organised 7 shared tasks covering both speech and text processing: speech synthesis, speech recognition, speaker verification, constituent parsing, multi-document summarisation, Chinese-Vietnamese machine translation, and multilingual visual question answering. The multilingual visual question answering task, combining natural language processing and computer vision, was introduced for the first time at VLSP 2022.

In the Emotional Speech Synthesis (ESS) task, the Speech World team from VinBigData won first place with a model that converts text into emotional speech. The system supports four emotions – neutral, sad, happy, and angry – with applications in film dubbing, virtual assistants, and audiobook narration. The technology has been refined since 2021 and is being transferred to commercial products.

In the Multi-lingual Speaker Verification task, the Voice Biometrics solution from Inter ITS won first place. The technology uses voiceprint recognition to verify individual identity, offering higher security than conventional authentication systems, with applications in banking, public administration, and e-commerce.

INT2 sponsored VLSP 2022 and supported its shared tasks with engineering and computing resources.

The 8th International Workshop on Vietnamese Language and Speech Processing (VLSP 2021) was held on December 18, 2021, hosted by the University of Information Technology, VNU-HCM. The workshop is organised annually by the Association for Vietnamese Speech and Language Processing (VLSP), a member of the Vietnam Association for Information Processing (VAIP).

VLSP 2021 featured 7 shared tasks evaluating Vietnamese text and speech processing tools, including speaker verification, speech recognition, and natural language processing. The workshop included scientific presentations, a panel discussion on developing the VLSP community, product demonstrations, and evaluation competitions. Datasets built for the workshop are shared with the entire community for research and application development, and the best experimental results serve as a reference for research groups selecting solutions for real-world problems.

Since 2020, the VLSP Club has been formally established as a chapter of the Vietnam Informatics Association, continuing the series of international VLSP workshops initiated in 2012 under the leadership of VLSP research groups at universities and institutes across Vietnam.

INT2 supported VLSP 2021 through engineering expertise and computing resources for the workshop and its evaluation activities.

The workshop was sponsored by the Vingroup Innovation Foundation (VinIF) and supported by a consortium of academic and industry partners including VinBigData, AIMESOFT, VBee, VTCC, VCCorp, IOIT, VNU-UET, VNU-HUS, USTH, TLU, UIT, JAIST, INT2, and InfoRe.
