Latest Patents

Wan Jie Chen holds a patent for an "Automatic de-identification of sensitive conversational audio data." This patent discloses techniques for automatically de-identifying sensitive information in audio conversations by integrating un-transcribed voice activity detection (VAD) with large language model (LLM) analysis. The audio de-identification system processes speech-to-text transcriptions while identifying segments where automatic speech recognition (ASR) failed to transcribe spoken content. These un-transcribed segments are represented as placeholders in prompts sent to an LLM, which analyzes the surrounding textual context to determine if sensitive information, such as personally identifiable information (PII) or protected health information (PHI), was likely spoken during these gaps. When sensitive content is identified, the system modifies the corresponding audio segments through an audio identification tactic. This approach addresses the technical challenge of incomplete de-identification in automated audio processing by leveraging LLMs' contextual understanding to detect sensitive information in segments that traditional ASR systems miss, particularly in scenarios involving poor audio quality or diverse accents. The result is a more comprehensive and reliable audio de-identification system.
