Frequently asked questions

What are AI voice agents? 
down arrow

AI voice agents are virtual assistants powered by artificial intelligence, speech recognition, and natural language processing. They process and respond to human conversations in real time. Voice agents can execute a variety of different tasks, like answering questions, taking messages, transferring calls, and booking appointments.

What is the best AI voice agent?
down arrow

The best AI voice agent depends on your business needs. If you run a healthcare business, your AI voice agent might require HIPAA compliance. For example, do you provide service to customers in multiple countries? Your AI answering service may require GDPR and multilingual support to work for you. 

Sona is the best AI voice agent for small and growing businesses. It reduces your missed calls, answers common customer questions, and takes detailed messages that make customer communication more efficient for your team.

How does an AI voice agent work?
down arrow

Here’s a quick breakdown of how AI voice agents work:

  • Speech recognition: Voice agents convert audio signals into text so that they can quickly process what is being said to them.
  • Natural language processing: Agents analyze the incoming text to understand the question or request. They identify specific actions or questions in a conversation. 
  • Complex reasoning: AI agents use a variety of functions and APIs to think through the right response for the initial request. They search through their knowledge base to provide a response. 
  • Generating a response: Using large language models or LLMs, agents generate a text response to the user’s query. 
  • Converting text to speech: Conversational AI voice agents convert text into speech with text-to-speech or TTS software. 

The best part about modern voice agents is that they operate with low latency. They can generate responses quickly and reduce wait times in a conversation. 

Can Sona and AI voice agents replace my sales and support teams?
down arrow

At this time, Sona and AI voice agents can’t perform all the functions of a sales or customer support team. For example, if you need to return an order or get a sales demo, an AI voice agent can’t handle those tasks yet. 

Dedicated sales AI or customer support AI tools are still limited in how much they can do for your team. They can plug into existing systems by handling additional inbound call volume when your team is busy or away for the day. However, they can’t replace human agents. They can’t work through complex tasks like customer complaints or escalations. 

AI voice agents vs. chatbots vs. human agents: which is better for small businesses?
down arrow

Voice agents, chatbots, and human agents serve different purposes for your small business:

  • Chatbots similar to OpenAI’s ChatGPT are useful for providing live chat support on your website. Support bots can integrate with your helpdesk software so that your team can follow up for more complex requests. 
  • Voice AI agents can provide phone support during business hours when your team is busy or after-hours support if your team is unavailable. They offer a more conversational approach to serving customer needs. 
  • Human agents can offer the most authentic and natural customer service. The problem is that human agents don’t scale as your call volumes grow. They’re also the most expensive option and are harder to train than chatbots and AI agents. 

Small businesses can use all three options to serve their customers. Given their budget and resource constraints, it may be better for them to lean on using chatbots and AI agents for most support requests. Small businesses can reserve their human agents for any troubleshooting or complex requests. That way, they don’t invest in adding more human agents too quickly. 

Do I get charged for spam calls?
down arrow

Sona calls that last less than 15 seconds aren't charged to you. This is to help you avoid getting charged for spam and robocalls. 

What happens if my AI voice agent can’t answer a question?
down arrow

If Sona can’t answer a question, it'll communicate the limitation to the caller and offer to take a message for a human team member to follow up.
