Questions & Answers

Q: How has Baidu transformed from a search engine into an AI company?

Baidu recognized the dynamic nature of the internet ecosystem in China and embraced the mobile revolution by remaking itself as an AI company.

Q: What is the role of Baidu's AI Lab within the company?

The AI Lab is responsible for understanding current AI research, conducting its own basic research, and translating that research into business and product impact for Baidu.

Q: Can you provide an example of how research from the AI Lab has been commercialized into a product?

Baidu has worked extensively on improving speech recognition technology, resulting in a speech engine called Deep Speech that is superhuman in performance, even for users with thick accents.

Q: How much data is required to train Baidu's speech recognition systems?

Baidu's speech recognition systems use a significant amount of data, with the English system requiring around 10 to 20,000 hours of audio. However, the lab is also exploring ways to develop machine learning systems that require less data for human-level performance.

Q: Could you explain the process behind training a speech recognition system?

To train a speech system, large amounts of audio clips are collected and annotated with correct transcriptions. A deep learning algorithm then learns to predict the correct transcription directly from the audio clips.

Q: What are the challenges in improving speech recognition technology?

One challenge is handling scenarios with crosstalk and background noise, as current systems struggle with these situations. The AI Lab is focused on tackling these challenges and enabling speech recognition for a wider range of applications.

Q: Are there any concerns about the ethics of emulating someone's voice with AI technology?

There are potential social challenges around the authenticity of AI-generated voices, which will require critical thinking and adaptation by users. However, the positive impacts of AI, such as helping individuals with disabilities, outweigh these concerns.

Q: Will AI create new jobs or lead to widespread job displacement?

While job turnover may increase with advancements in AI, the need for continual learning and adaptability will become more important. The field of AI will require professionals who can understand and contribute to research, as well as think about product development and user experience.

Summary & Key Takeaways

• Baidu is the largest search engine in China and is transitioning into an AI company.
