Role brief

aimlroles summary, based on the employer's posting.

What you'll do

  • Build speech and audio generation methods using LLMs, including text-to-speech, voice conversion, and sound or music creation
  • Improve speech and audio systems for online use, focusing on effectiveness, efficiency, and scale
  • Advance real-time spoken interaction by exploring streaming and full-duplex multimodal LLM capabilities
  • Work with research and engineering teams to move ideas from prototypes into production

What you bring

  • A Ph.D. in computer science, electrical engineering, signal processing, or another closely related field
  • Strong speech and audio processing knowledge, plus experience with modern generative models
  • Practical experience adapting LLMs to speech or audio, such as through speech tokenizers or joint speech-text training
  • Proficiency in Python and deep learning frameworks such as PyTorch
  • Publications at leading venues such as ICML, NeurIPS, ACL, or another listed venue

Who this fits

This senior research role suits someone with doctoral training and hands-on work extending LLMs into speech or audio. The position is based in Singapore.

From the employer

Business Unit

LIGHTSPEED STUDIOS is made up of passionate players who advance the art & science of game development through great stories, great gameplay, and advanced technology. We are focused on bringing next generation experiences to gamers who want to enjoy them anywhere, anytime, across multiple genres and devices.

About the Hiring Team

Lightspeed Tech Center is a R&D department under Lightspeed Studios which develop PUBG Mobile and other high-quality games. Our Tech Center leads the research, exploration, and discovery of innovative technologies and provides technical services for all games during all phases of life cycle, including engine, audio, QA, AI, next generation game, technical cooperation, etc.

What the Role Entails

  • Research and develop advanced speech synthesis and generation algorithms (e.g., TTS, voice conversion, sound/music generation) based on LLMs, multimodal/omnimodal LLMs.
  • Develop and optimize speech and audio synthesis systems for online applications, improving effectiveness, efficiency, and scalability.
  • Explore and advance full-duplex/streaming multimodal LLM capabilities in speech understanding, generation, and real-time spoken interaction.
  • Collaborate cross-functionally with research and engineering teams from prototyping to production.

Who We Look For

  • Ph.D. in Computer Science, Electrical Engineering, Signal Processing, or a closely related field.
  • Strong foundation in speech/audio processing and modern generative models (e.g., diffusion, flow matching, autoregressive, codec-based approaches).
  • Hands-on experience extending LLMs to speech/audio modalities (e.g., speech tokenizers, multimodal adapters, speech-text joint training). Experience with full-duplex or streaming spoken dialogue systems and real-time interaction modeling is a plus.
  • Proficient in Python and deep learning frameworks (e.g., PyTorch); experience with distributed training is a plus.
  • Track record of publications at top-tier venues (e.g., ICML, NeurIPS, ICLR, ACL, ICASSP, Interspeech).
