Dear Innovation, Technology and Industry Bureau Digital Policy Office,

I am writing under the Code on Access to Information about the artificial intelligence used in the 1823 service. On 27 August 2026 the Digital Policy Office announced that 1823 operates an intelligent interactive telephony system using voice recognition, and that the "Call Assistant" project uses speech recognition and large language models to transcribe calls and generate case summaries. I would like the following records.

1. Please provide the tender documents or the contract award notice that name the contractor or contractors for the interactive telephony system and for the "Call Assistant" project.

2. Please provide the technical specification or project document that names the AI models and speech-recognition engines used by those two systems.

3. Please provide the recorded accuracy or error rate of the speech-recognition and language-model functions, and the procedure for checking or correcting a transcript before it is used to update a case record.

Scope limiter: if the records requested are not held in the form described, please provide the nearest equivalent record that is held. If you refuse any part of this request, please state the provision of the Code on Access to Information relied on.

Yours faithfully,
CHEN Zhengxian
