Financial Organizations across the globe are keen and in the process of adopting BOT technology to improve automation, enhance customer experience & reduce overall operation costs.

What is conversational AI in contact center?

Conversational artificial intelligence (AI) is a technology that makes software capable of understanding and responding to voice-based or text-based human conversations. It uses machine learning; natural language processing understands user intent and form responses. Bots can continuously learn from conversations with customers, so they’re able to deliver more helpful responses as time goes on. 

Interface provide user to interact with back-end system using natural language say English, and this interface called as conversational interface. Conversation is the exchange of messages between end user and BOT to complete specific tasks.

Customer/User will say in different ways, words, dialect & accent, are the major Challenge to design conversational BOT. This can be addressed with the help of Natural Language processing Engine (NLP Engine), its NLP engine of Virtual assistance make sense of human language that is meaning full. NLP is used to determine a user’s intention (Intent Recognition) and to extract information (Entity Extraction) from the user’s utterance and to carry on a conversation with the user to execute and complete the task. The responsibility of NLP engine is to understand or qualify user intent and extract Entity/variable and store in data table to use for processing. NLP Engine supports multiple languages. Currently Contact Center platforms are offers with native BOT capabilities or easy integration with known players in the market. The focus is on improving self-service, allowing omnichannel customer interaction, real time guidance to customer service agents.

Evolution of Bots

Basic FAQ BOT (1st Gen)- Action BOT (2nd Gen)- Intelligent BOT (3rd Gen)- Generative AI BOT(4th Gen)

Components of Conversational AI:

1. Machine Learning

Machine learning consists of algorithms, features, and data sets that systematically improve over time. The AI recognizes patterns as the input increases and can respond to queries with greater accuracy. Success of conversational AI depends upon % accuracy in understanding customer intents & can be able to predict accurately

2. Natural Language Processing

Conversational AI uses NLP to analyze language with the aid of machine learning. Language processing methodologies have evolved from linguistics to computational linguistics to statistical natural language processing. Combining this with machine learning is meant to significantly improve the NLP capabilities of conversational AI in the future. Natural Language Processing (NLP) Engine and its key tasks to understand user utterance or intent & attributes/variables.

3. Data

The success of conversational AI depends on training data from similar conversations and contextual information about each user. Using demographics, user preferences, or transaction history, the AI can decipher when and how to communicate

4. Conversation Design

Conversational Design is a crucial step toward deployment. The first step is to understand all possible questions customers may ask & define appropriate responses from the BOT, to build a conversation prototype. This prototype should then be reviewed and agreed upon with multiple stake holders before moving on to the building phase.

 How Does Conversational AI Work? 

Conversational AI allows humans to interact with machines through four steps:

Step 1: It starts with receiving information from humans, which may be written text or spoken words. As the input is spoken, voice recognition converts it into text by Speech to Text (ASR) that is in a machine-readable format.

Step 2: The second step is for the application to grasp what the text means. To understand the intent behind the text, conversational AI uses natural language understanding (NLU) – a part of NLP algorithms.

Step 3: Utilizing dialog management, the application determines the response based on its understanding of the text’s intent. By orchestrating responses and converting them into a human-readable format through natural language generation (NLG), dialog management forms the other aspect of NLP. For Voice, it converts text back to speech by Text to Speech (TTS) that is understandable to the user with proper accent & dialect. Depending upon user or customer conversation it kicks start the automation to bring relevant dynamic data to present back to user and store for future use. With advancement of technology and shift in customer adoption, it is feasible to integrate with LLM to bring more human like conversation.

Step 4: Depending on the platform, either the application delivers the response in text or uses speech synthesis (artificial generation of human speech) so that the user receives it over a voice channel or irrespective of channel of customer choice.

Performance of Conversational AI

It depends on multiple factors stated below:

  1. Conversational Design

Considering all possible conversations, the user may need to satisfy specific requirements. Conversational designers will play a key role in designing conversation for specific Business use cases.

  1. Right ASR & TTS engine for voice communication

Customer preferences to have voice conversation and demand to select right ASR, TTS engine are challenges. % Fail to understand customer intents and proper response where user can understand it better.

  1. NLP configuration & Training

Understanding the intent behind the text & generating the right response is very crucial for NLP engine. Intent Identification is the key parameter for success of any conversational design. Regular and the right amount of training is very crucial. NLP engineers must monitor the failure intent and ensure regular training to improve accuracy in intent detection and better response.

  1. Platform offering

 ASR/TTS Integration with NLP Engine

NLP Platform supports native ASR/TTS for Voice BOT, and it is flexible to integrate with 3rd party ASR/TTS tools such as Deep gram, Eleven Lab, AWS Transcribe, Microsoft, Google etc.

Automatic Speech Recognition (ASR) performance measured with the parameters below:

WER (Word Error rate) - is a common metric of the performance of a speech recognition or machine translation system. The WER metric ranges from 0 to 1, where 0 indicates that the compared pieces of text are identical, and 1 indicates that they are completely different with no similarity. WER is the ratio of errors in a transcript to the total words spoken. For example, a 20% WER means the transcript is 80% accurate. ASR systems developed by Google, Microsoft and Amazon have a WER of 15.82%, 16.51% and 18.42% respectively.

WIL (Word Information Loss). This value indicates the % of characters that were incorrectly predicted. The lower the value, the better the performance. Word information loss rate of 0 being a perfect score.

TTS: - the task of generating natural sounding speech for the given text input.

Consideration of Conversational AI integration with contact center platform

Contact Centers providers now offer native BOT capabilities; however, it also allows to integrate external BOT platforms for the specific Business use cases & better performance. Below are the possible integration approaches with external BOT platforms.

Approach 1: - Contact Center IVR+ASR/TTS integration with conversation AI.

Approach 2: - Contact Center IVR integration with conversation AI ASR/TTS.

How to boost conversational experience with Gen ai?
