  • Pattern-aware data augmentation for query rewriting in voice assistant systems
    Yunmo Chen, Sixing Lu, Xing Fan, Yang Fan, Xiaojiang Huang, Chenlei (Edward) Guo
    AAAI 2021 Workshop on Reasoning and Learning for Human-Machine Dialogs Workshop (DEEP-DIAL21)
    2021
    Query rewriting (QR) systems are widely used to reduce the friction caused by errors in a spoken language understanding pipeline. However, the underlying supervised models require a large number of labeled pairs, and these pairs are hard and costly to be collected. Therefore, We propose an augmentation framework that learns patterns from existing training pairs and generates rewrite candidates from rewrite

  • Efficient large scale semi-supervised learning for CTC-based acoustic models
    Prakhar Swarup, Debmalya Chakrabarty, Ashtosh Sapru, Hitesh Tulsiani, Harish Arsikere, Sri Garimella
    SLT 2021
    2021
    Semi-supervised learning (SSL) is an active area of research which aims to utilize unlabeled data to improve the accuracy of speech recognition systems. While the previous studies have established the efficacy of various SSL methods on varying amounts of data, this paper presents largest ASR SSL experiment ever conducted till date where 75K hours of labeled and 1.2 million hours of unlabeled data is used

  • Cloud-based automatic building and road extraction from large scale open geospatial datasets
    YZ Shi, Tianyu Zhang, Daniel Hogan, Jake Shermeyer, Adam Van Etten, Xin Chen
    WACV 2021
    2021
    We author Jupyter notebooks to develop deep learning models on Amazon SageMaker instance. These models automatically extract building footprints and road networks from open geospatial datasets. The notebooks reproduce winning algorithms from the SpaceNet challenges. In addition to the SpaceNet satellite images, we introduce USGS 3D Elevation Program (3DEP) light detection and ranging (LiDAR) data to the

  • Inverse reinforcement learning with natural language goals
    Li Zhou, Kevin Small
    AAAI 2021
    2021
    Humans generally use natural language (NL) to communicate task requirements to each other. Ideally, NL should also be usable for communicating goals to autonomous machines (e.g., robots) to minimize friction in task specification. However, understanding and mapping NL goals to sequences of states and actions is challenging. Specifically, existing work along these lines has encountered difficulty in generalizing

  • Towards semi-supervised semantics understanding from speech
    Cheng-I Lai, Jin Cao, Sravan Bodapati, Shang-Wen Li
    NeurIPS 2020 Workshop on Self-Supervised Learning for Speech and Audio Processing
    2020
    Much recent work on Spoken Language Understanding (SLU) falls short in at least one of three ways: models were trained on oracle text input and neglected the Automatics Speech Recognition (ASR) outputs, models were trained to predict only intents without the slot values, or models were trained on a large amount of inhouse data. We proposed a clean and general framework to learn semantics directly from speech

Principal Applied Scientist, Real-Time Conversational AI , AGI
US, WA, Seattle
We are looking for a Principal Applied Scientist to drive the research and development of real-time multimodal conversational AI. You will operate across two focus areas: advancing foundation models for speech and audio, and building the post-training systems (reward modeling, reinforcement learning) that shape natural, human-like conversational behavior. You will be the expert in your area while contributing across the full model lifecycle — from pre-training and architecture design through post-training alignment and real-time deployment. You will work at the frontier of what's possible in conversational AI, with the compute, data, and runway to pursue problems that few teams in the world have the resources to tackle. As a Principal Scientist, you will set the technical direction for your research area, influence the broader roadmap, and work closely with inference engineers to ensure your models are designed for real-time production deployment from inception. Key job responsibilities Foundation Model Scaling - Build and train large-scale multimodal foundation models for real-time speech and audio generation, from architecture design through production-scale training - Advance the scaling and efficiency of conversational modes, including the relationship between data, model size, and real time performance. - Design model architectures informed by hardware constraints and inference requirements, working with inference engineers to ensure models are servable from inception - Develop training methodologies for multimodal models that jointly process and generate speech, language, and audio in real-time streaming contexts Post-Training & Reinforcement Learning - Design and build reward models and reward functions for speech systems — capturing naturalness, fluency, conversational quality, and real-time responsiveness - Develop and apply reinforcement learning methods to shape conversational behavior — teaching models natural timing, responsiveness, and fluid interaction - Build the post-training pipeline from SFT through RL alignment, optimized for real-time multimodal outputs rather than text-only generation - Design evaluation frameworks that capture the quality dimensions unique to real-time conversation Real-Time Perception & Generation - Advance the team's capabilities in real-time perception - Work at the intersection of model architecture and production constraints to ensure multimodal capabilities function within hard real-time latency budgets
