Looking for the best AI voice bots to automate your business operations?

Automated voice assistants are becoming tremendously popular as more businesses across different industries are looking for effective ways to automate their customer service and sales operations. No wonder the market is literally booming. In fact, the global voicebot market size is estimated to reach $98.2 billion by 2027, growing at a CAGR of 18.6% from 2022 to 2027, according to an IndustryARC report.

In this article, we’ll explore the best AI voice bots for automating your business operations, along with the key features and capabilities each solution offers. Whether you’re looking to automate your customer service or outbound sales operations, these solutions are definitely worth your attention. 

What are AI Voice Bots?

AI voice bots (otherwise known as AI voice agents or AI phone agents) are AI-powered software solutions that can understand spoken language and respond to users in a natural, human-like way using technologies like Automatic Speech Recognition (ASR), Natural Language Processing (NLP), and text-to-speech (speech synthesis), among others. 

AI voice bots can handle inbound calls automatically, provide information about your products or services, answer FAQs, and perform actions like scheduling appointments or updating customer records in CRM. Some of the most advanced solutions can also initiate and handle outbound calls independently. 

Why Use AI Voice Bots for Automating Your Business Operations?

AI-powered voice bots are excellent solutions for customer service and sales automation. Here are some of the key benefits of implementing an AI voice bot solution: 

• Deliver 24/7 customer support: AI voice bots in customer service can operate 24/7, answering inbound calls and helping customers get information or resolve issues independently, even when your human agents aren’t available. Plus, besides answering FAQs, AI voice bots can perform real actions like tracking orders, processing returns, updating subscriptions, or checking account balances.

• Improve customer experience: Research by Invoca shows that 5% of callers hang up as soon as they’re put on hold, 28% hang up within five minutes, and just 6% are willing to wait 30 minutes or more. With an AI voice bot that can answer calls immediately, you can reduce frustrating wait times, improve customer experience, and ultimately increase customer satisfaction. 

• Automate appointment scheduling: AI voice bots can easily automate the entire process of appointment booking and managing rescheduling requests. They can integrate with calendar and scheduling software tools to effortlessly book, confirm, and reschedule appointments without human intervention. That can help you reduce admin workload and free up your team to focus on complex requests.

• Pre-qualify and capture leads: AI voice bots aren’t just great at automating customer service operations. They can handle the initial lead qualification by asking your leads a series of pre-qualification questions, accurately capture lead details, and automatically update records in your integrated CRM system, helping you streamline your entire lead qualification process. 

• Automate proactive outreach: AI voice bots can help you automate proactive outreach campaigns for service notifications, reminders, or feedback collection. You can also use them to automate your cold calling campaigns, saving your sales team time and effort by eliminating the need to engage with unqualified or uninterested prospects.

• Reduce call center costs: With the ability to handle thousands of concurrent calls and interact with customers or prospects in different languages fluently, implementing an AI voice bot for customer service or sales automation can help you reduce your call center costs significantly, which is especially true for businesses with high call volumes. 

Key Features and Capabilities of AI Voice Bot Solutions

Not all AI voice bot solutions are built equally. Here are the key features and capabilities you’ll find with some of the most advanced AI voice bot providers: 

• Ability to handle inbound and outbound calls: AI voice bots can handle both inbound and outbound calls, allowing you to automate customer support and outbound calling campaigns.

• Support for multiple languages: AI voice bot solutions can handle conversations in multiple languages, which might be critical for businesses with truly global call center operations. 

• Ability to handle simultaneous calls: AI voice bots can handle hundreds or thousands of calls at once, enabling you to reduce call center costs while managing large call volumes effectively.

• Seamless hand-offs to human agents: AI voice bots can escalate calls to human agents when needed without losing any context, so an agent can easily pick up from where the voice bot left off.

• Intelligent interruption handling: AI voice bots can intelligently handle interruptions or overlapping speech without breaking the conversation flow, allowing for natural-sounding conversations.

• Integrations with CRM and other back-end systems: AI voice bots can integrate with CRM platforms, calendar software, payment apps, and other back-end systems and perform actions within those systems.

• Call reporting and analytics: With reporting and analytics features, you can track specific metrics and KPIs to evaluate your voice bot’s performance and understand where improvements are needed.
