Voice Bots is a poweful tool that allows automated responses and routes customers' and your team’s queries via bot assistance. There are several Voice Bot integration types:

• Generative AI let you create highly interactive and intelligent Voice Bots without any coding expertise. By providing specific instructions, the AI model generates dynamic, context-aware responses that enhance user engagement. You can also create easily incorporate custom functions to interact with third-party servers, allowing your bot to perform actions like fetching real-time data, updating records, or triggering external processes during a conversation. This option doesn’t require coding experience.

• Webhooks and AWS SQS allow you to take full control over your voice bot sessions. These options are ideal if your voice bot requires custom handling of conversations; you can build a service to analyze events and generate responses.

• Dialogflow CX is aversatile AI platform, which is great at handling natural language and managing conversations, even when they get a bit complicated. It is good for automating customer interactions, handling queries, and passing customers to agents when needed, especially in cases where you have clear predefined use cases of customer interactions, where the scenarios of communication with customers are generally the same.

• OpenAI Assistant connects your Voice Bot to OpenAI’s language models, which lets to handle complex conversations and provide natural responses to user queries. With OpenAI’s advanced AI capabilities, your Voice Bot can understand context, manage dialogues, and deliver personalized interactions.
