Siri is becoming more and more "popular". What breakthroughs will there be in smart voice in the future?

For human-computer interaction, how to make machines have good hearing has been a goal pursued unremittingly in the field of AI in recent years. Around 2009, deep learning model applications began to leave the academic world, and intelligent speech technology represented by speech awakening, recognition, enhancement, and synthesis also gradually matured.

A typical early example is the birth of siri in 2011. Intelligent voice has become a new leap in the way of communication and interaction between humans and machines. After more than ten years of development, "Hey, Siri"-style human-machine question and answer is no longer limited to mobile terminal devices, has entered thousands of households, and is widely used in various scenarios: smart speakers for home companions, and Tmall Genie for convenient online shopping. , simultaneous translation at meetings, car voice navigation assistants when traveling, etc.

As more and more Internet companies and upstream manufacturers actively deploy in the intelligent voice track, products such as intelligent voice customer service, conversational AI applications, and AI virtual assistants have achieved great success. With further quality improvement, the response voice is more natural, the understanding of questions is more accurate, and it has its own "little emotions".

In the era of digitalization, the trend of interconnection of everything is unstoppable. Intelligent voice, as the key interface for current human-computer interaction, is in a period of deep integration and collision with the real economy. With the further development and expansion of application scenarios, we have also seen many challenging problems, such as: how to identify the speaker's identity, how to identify dialects, how to eliminate ambiguity, etc. are the latest research hotspots.

Behind the maturity of a technology, there is often some potential, including its innovative ability in practical applications and its more potential evolution direction. Looking to the next stage, intelligent voice technology will also see new evolution trends. For example: Can deeply integrated AI voice chips replace the cloud model running model? Can innovative research on multi-modal fusion, unsupervised learning, and cross-integration of brain disciplines achieve breakthrough results? We'll see.

So, what real production problems have been encountered in the practical exploration of intelligent voice technology in major enterprises? How was it solved? What progress has been made? What new changes have occurred in the industry? What are the next development trends? The "AISummit Global Artificial Intelligence Technology Conference" intelligent voice technology special session will bring you in-depth thinking!

On August 7th, the “AISummit Global Artificial Intelligence Technology Conference” dedicated to intelligent voice created by 51CTO is coming!

What special topics are you interested in?

Topic 1: Zuoyebang Speech Technology Practice

1. Exploration of speech recognition technology: Share speech recognition technology in large-scale practical application scenarios such as end-to-end, efficient use of data, etc. And a hot word technical solution based on prefix automata was proposed.
