Conversational artificial intelligence

Mandarin to English

Chethan Kumar, November 28, 2020: The Times of India

A Bengaluru firm with expertise in conversational artificial intelligence (AI) has developed an integrated speech recognitionbased solution that can help interpret cross-border intercepts along India’s northern and north-eastern borders.

Its product delivered last year, is being used by the armed forces on the western and eastern borders.

The system developed by uses automatic speech recognition (ASR), machine translation and speech-to-text to convert Mandarin to English. The firm used more than 8,000 hours of audio data — four major dialects of Mandarin — to train the machine, and the firm’s co-founder and CTO Ananth Nagaraj said the tool would strengthen the armed forces.

The applications include cross-border intelligence, voice surveillance, monitoring telephone/internet conversations, intercepting radio/satellite communication and bridge interactions during border meetings and joint exercises. Some features are noise reduction, dialect/accent detection and support for all audio file formats. “We’re in talks with the armed forces and confident of this being accepted,” Nagaraj said.

He said the armed forces, which had intercepts from various sources, would earlier use either manual analysis or keyword-based search technology. Gnani’s solution used AI and provided a complete transcript of millions of records within hours.

Nagaraj said the the armed forces do not have enough expertise in Mandarin compared to the languages used in Pakistan, Bangladesh or Nepal.
