Approximately, seven years before speech recognition was not as lucrative as it looks today.
Error ratio was so high that the developers were reluctant to launch an application with speech recognition for the public.
But thanks to some of the robust digital signal processing techniques which were instrumental to increasing the rate of accuracy.
It is also playing a key role in automotive telematics, mobile phone technology, conferencing system and similar telecom applications.
Digital signal processing uses reconstruction filters to overcome background noise and noise reduction.
In analog processing, there is no big scope of using sophisticated signal processing due to its non-dynamic nature.




The global AI market is divided on the basis of technology, industry vertical, and geography.
Based on technology, the market is segmented into machine learning, natural language processing, image processing, and speech recognition.
The machine learning segment held the largest share in 2016, contributing more than half of the market and expected to maintain its dominance throughout the study period.
Moreover, the segment is projected to register the fastest CAGR of 56.4% during the forecast period.The global artificial intelligence market was pegged at $4.06 billion in 2016 and is projected to reach $169.41 billion by 2025, registering a CAGR of 55.6% from 2016 to 2025.Rise in investment in AI technologies, increased demand for analyzing and interpreting large amount of data, and surge in customer satisfaction coupled with increase in adoption of reliable cloud application have boosted the growth of the global artificial intelligence (AI) market.
However, dearth of trained and experienced staff hampers the market growth.
On the contrary, rise in adoption of AI in emerging markets and rapid development of smarter robots are expected to create lucrative opportunities in the near future.Based on industry vertical, the market is divided into media & advertising, BFSI, it & telecom, retail, healthcare, automotive & transportation, and others.
