A voice bot, also known as a voice assistant, is a type of bot that uses natural language processing (NLP) and text-to-speech (TTS) technology to interact with users via voice commands. Voice bots are designed to respond to spoken requests and provide information or perform tasks in a conversational manner.
One key difference between voice bots and regular chatbots is the way they interact with users. Voice bots use speech recognition to understand spoken requests, while chatbots use text recognition to interpret written requests. Additionally, voice bots are designed to provide a more conversational experience.
We recently worked with a client who was transitioning from a traditional live agent to a voice bot for the customer services duties for their teletherapy application.
Callers are distributed in multiple countries and regions. With hundreds of potential callers, managing who each user needs to reach can become complicated. Generally, several operators were on duty taking calls. The operator talks to the caller and asks them who they want to talk to. Then the operator proceeds to do a (warm) transfer to the appropriate agent. If the agent is not available, the operator sends the caller to voicemail to leave a message.
Our client trained the voice bot with some frequent questions and answers. For example, requesting to connect to an agent and providing a name or some identification. They are also adding a language selector to be able to ask and answer questions in other languages.
Initially the bot was trained as a chat bot, but our client wanted to provide this capability and more to the callers.
One approach that might be helpful in standardizing your solution is to leverage existing protocols built for managing media in voice applications. MRCP (Media Resource Control Protocol) is used for managing media resources in voice and speech applications. It enables communication between application servers and media servers for tasks such as speech recognition and synthesis.
Once that media connection is established it can forward it to TTS or ASR services and then to SLU or LLM that provide responses and that we can forward back to the IP-PBX.
If you prefer something more custom, you can also directly connect like an additional participant and capture that media and forward RTP to the third party service you want or even have your own custom bot service built in house.
Artificial Intelligence (AI) is moving out from science fiction stories to something we also use everyday. Voice bots are just one example.
