We sat down with Voiso Product Manager Oleg Tuns to discuss the integration of TTS into our platform, its benefits, challenges faced during development, and future enhancements that our users can look forward to.
Takeaways
- Text-to-Speech (TTS) automation reduces human agent workload by handling routine inquiries and providing self-service options, enabling 24/7 support and faster response times.
- TTS currently supports over 20 languages, offers cost-effective deployment, and allows customization of synthesized speech, although enhancing naturalness and regional accent support remains an opportunity.
- For agents, TTS improves efficiency, decreases handling time, and enhances customer satisfaction; for managers, it delivers cost savings, scalability, and operational flexibility.
- Development challenges included real-time responsiveness and handling large volumes of text across geographically distributed systems, which were addressed through system optimization.
- Upcoming TTS enhancements include features like “Collect Digits,” voicebot interactions, and improved speech recognition accuracy and speed.
- TTS is designed to complement, not be replaced by, Intelligent Virtual Agents (IVAs), remaining a critical component in conversational AI solutions.
- Continuous improvement of TTS voice quality, feature expansion, and integration with IVAs positions the platform to deliver a more natural, efficient, and satisfying customer service experience.
Our Conversation with Oleg Tuns
Q: What was the initial catalyst for incorporating TTS into our roadmap?
A: The initial catalyst was our desire to automate customer service interactions in a more efficient and cost-effective way. By using TTS, we could reduce the need for human agents to handle routine inquiries, allowing them to focus on more complex issues. Additionally, TTS enables us to provide support in multiple languages and dialects, making it easier to serve our global customer base.
Q: Based on your experience, what are the key advantages and limitations of our current TTS implementation? Where do we excel, and where do we see opportunities for improvement?
A: Our TTS implementation has several key advantages. First, it offers wide language support by including over 20 languages out of the box, which allows us to serve a diverse customer base effectively. Second, we provide competitive pricing, making our TTS solution a cost-effective option for businesses. Third, the system allows for customization of the synthesized speech, enabling us to tailor it to specific regional accents and business requirements.
However, we’ve identified areas for improvement. While our current voices are good, there’s an opportunity to make them sound more natural and human-like. Additionally, although we can customize speech to some extent, providing highly specific regional accents, such as a Texan accent, presents limitations. Overall, our current TTS implementation is a solid foundation, but enhancing voice quality and regional accent support will further improve the user experience and add value for our customers.
Q: What are our users’ most common pain points and jobs-to-be-done (JTBD) that TTS addresses well?
A: Many businesses struggle with overwhelming inbound traffic, handling large volumes of calls and inquiries. Customers often experience long wait times when trying to reach a human agent, and routing calls to the appropriate agents can be time-consuming and error-prone. TTS addresses these pain points effectively by automating routine inquiries and providing self-service options, which reduces the workload on human agents. Users aim to offer consistent and timely support to customers, even outside of regular business hours, thereby providing 24/7 support. By reducing wait times and delivering accurate information, they strive to improve customer satisfaction.
Q: Can you tell us what the most impactful value is for each type of user, please?
A: For customer-facing roles such as contact center agents and customer support staff, TTS reduces their workload by automating routine inquiries, allowing them to focus on more complex issues. It improves efficiency by providing quick and accurate responses, streamlining interactions, and reducing handling time per call. Moreover, it enhances customer satisfaction by offering consistent, 24/7 support, which reduces wait times and improves the overall customer experience.
For business owners and managers, TTS brings cost savings by automating routine tasks, thus reducing the need for additional staff. It increases efficiency by improving overall operational productivity. Enhanced customer satisfaction can lead to increased loyalty and revenue. TTS also offers scalability, handling increased call volumes without requiring more human resources, and provides flexibility by easily integrating into existing systems and workflows.
Q: Did the product and development teams face any challenges during the building phase?
A: Yes, we faced several challenges. The primary ones centered around ensuring a real-time experience for callers and handling large volumes of text. Specifically, we had to optimize for geographical distribution because, given our distributed infrastructure, we needed to ensure that callers received quick responses regardless of their location. We also needed to handle large text inputs, requiring the system to process and synthesize speech from extensive text without significant delays. We addressed these challenges through careful optimization and design of the TTS system, ensuring it delivers a high-quality experience for users.
Q: What are the upcoming developments that would directly benefit TTS that our users could expect?
A: We’re excited about several features in the pipeline. “Collect Digits” is already in production and will be announced soon. This feature allows users to input numerical data, such as phone numbers or account numbers, directly through voice commands, which streamlines interactions. We’re also considering building a voicebot feature that enables users to interact with the system using voice commands, enhancing the conversational experience and simplifying access to information and task completion. Additionally, improving the accuracy and speed of speech recognition will allow the system to better understand user inputs and provide more accurate responses.
Q: Do you see our Flow Builder’s TTS Node being deprioritized or replaced by Intelligent Virtual Agents (IVA, aka AI Agents)?
A: No, we envision a collaborative relationship between the two. Intelligent Virtual Agents will likely incorporate TTS as a key component. IVAs consist of three main components: AI infrastructure, which is the underlying intelligence enabling the IVA to understand and respond to user inputs; Text-to-Speech, which is the ability to generate speech from text; and Automatic Speech Recognition, which is the ability to recognize and understand spoken language. While IVAs may introduce new capabilities, TTS will remain a crucial component for providing a natural and conversational user experience.
Closing Thoughts
Integrating TTS into our platform marks a significant step toward enhancing automated customer service. By continuing to improve voice quality and expand features, we’re committed to delivering exceptional value to our users and their customers. TTS, alongside advancements like IVAs, will play a vital role in the future of customer interactions, ensuring efficiency and satisfaction in every engagement.
