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 is honoured to continue sponsoring VLSP activities with human resources and computing resources, a commitment that began in 2008 with the VLSP Project.
