Generative speech – scaling universal vocoder to new limits

In artificial intelligence and speech synthesis, the quest for more natural and realistic voice interactions is a priority. At PolyAI, we’re committed to creating customer-led voice assistants. This means voice assistants that give callers the freedom to speak however they like and the confidence that they will receive useful responses. While we do a lot […]

Modular Intent Design: A More Effective Way of Understanding Language

NLU for Dialogue is a Unique Machine Learning Problem Consider speech recognition. This is a machine learning problem that also requires a lot of data. This data can be annotated relatively simply by a person listening to a recording and transcribing what is said.  With machine translation, there are many different ways to annotate data […]

How to Deploy Conversational AI for Voice

APPROACH 1 DIY, from scratch Some companies opt to build their own DIY voice assistant in-house, from scratch.  Bank of America’s “Erica” Bank of America did just that with their AI-driven virtual financial assistant: Erica. This completely self-owned system was created by a development team of 100 people in 2017. It took the team nearly […]

Nikola Mrkšić on the Practical AI Podcast

PolyAI CEO & Co-Founder Nikola Mrkšić spoke to Daniel Whitenack and Chris Benson last week on the Practical AI podcast. The topic of the podcast is next-gen voice assistants, and Nikola takes Daniel and Chris on a deep dive into conversational AI, discussing the next generation of voice assistants that will be capable of handling […]

PolyAI Maintains Lead Over IBM Watson Assistant and Other Popular Language Understanding Models

In December 2020, the team at IBM published a blog post and technical paper in which they benchmarked the performance of a new-and-improved Watson Assistant against other conversational AI platforms from Google, Microsoft and Rasa. Naturally, we were very curious.  As it happens, some of the training datasets used in the benchmark test were the […]

Conversational ID&V vs Voice Biometrics: A New Approach to Authenticating Customers on Customer Service Calls

Language is full of characters and words that sound frustratingly similar. Sorry, was that M or N? Did you say three, free, or tree? In normal conversation amongst friends, this is easily overcome but customers are less forgiving when they have an issue with a product or service. Before customers even get the opportunity to […]

How Voicebots Handle Languages & Accents

Let’s face it. Understanding your customers isn’t always easy. They tell stories, go off track and they often can’t think of a good way to explain an issue to you. And those are just the customers that speak the same language as you. Even for humans, it can be really difficult to understand people with […]

PolyAI’s ConveRT Model Outperforms BERT and GPT-Based Models in Salesforce Research Evaluation

In a recent evaluation by Salesforce Research, PolyAI’s ConveRT model performed top across a range of metrics, while using a fraction of the computational resources. Salesforce’s recent paper, Probing Task-Oriented Dialogue Representation from Language Models, compared ConveRT to other pre-trained models, evaluating their ability to encapsulate conversational knowledge in application to Conversational AI tasks. ConveRT […]

ConVEx: How PolyAI created the most accurate value extractor on the market

We’re thrilled to announce our recently published paper on the PolyAI ConVEx framework. Our new technique, ConVEx (Conversational Value Extractor), is the most accurate value extractor on the market. It requires significantly less data than previous best systems, which means that PolyAI can create virtual assistants faster and better than anyone else, across any customer […]
