Exploring Voice AI in Healthcare Administration: Super Dial's Approach & The Last Mile Problem

Hi everyone, I'm Nick, an engineer at Super Dial, and today I'll be sharing my insights on voice AI, its applications, and the unique challenges of being a voice AI engineer.

1. Nick is an engineer at Super Dial and gave a talk on voice AI at an event.
2. The field of voice AI is rapidly evolving, with new smart devices and text-to-speech models that support complex conversational use cases.
3. However, there are still challenges in converting chat agents to voice agents, such as dealing with audio hallucinations, pronunciation, and spelling.
4. There has been an explosion of voice AI infrastructure, tools, and evaluation systems, leading to the question of what is worth owning.
5. Super Dial has a platform that specializes in phone calls, particularly for healthcare administration businesses, and offers a service where they make calls on behalf of clients and provide structu
6. Super Dial uses a combination of voice bots and human agents to ensure reliable call completion, and aims to learn from each call to improve future interactions.
7. Voice AI can save time and resources by automating repetitive tasks, but it is important to consider ethical implications such as bias and accessibility.
8. When building voice AI applications, it is important to focus on conversation design and user experience, including questions like whether to use open-ended or closed-ended responses.
9. Super Dial uses Pipacat for voice AI orchestration, which is an open-source framework that is easy to extend and customize.
10. When working with large language models (LLMs), it is important to consider issues such as latency and the need for typed endpoints.
11. Self-hosting tools like Lane Fuse can be helpful for logging and observability, especially in regulated industries like healthcare.
12. Text-to-speech systems must be able to accurately communicate sensitive information like passwords and member IDs.
13. It is important to review recordings of voice interactions to ensure that they sound natural and accurate.
14. When building a voice AI persona, it is important to consider factors such as name pronunciation and user-friendliness.
15. Upgrade paths and fallbacks are crucial for maintaining high videoion accuracy and ensuring system reliability.
16. End-to-end testing of voice AI applications can be challenging, but tools like Telephony and Koval can help with testing and generating simulated interactions.
17. It is important for voice AI engineers to choose their stack wisely and focus on the unique aspects of their conversational experience.
18. The field of voice AI is rapidly evolving, and it is important to stay up-to-date with new models and tools while ensuring safe and ethical use.
