What is voice analytics?
Voice analytics is a sophisticated technology that decodes, analyzes and draws conclusions from voice data collected during customer interactions to gain insights and improve customer experience.
Voice analytics has journeyed from simple speech-to-text transcription to becoming an empathetic listener. Initially, it was about documenting dialogues via speech analytics, then it expanded to understanding semantics. Today, it can interpret emotions, intentions and contextual nuances via sentiment analysis.
With voice recognition, natural language processing (NLP) and artificial intelligence, voice analytics enables a better understanding of customer needs, preferences and behaviors.

The science behind the working of voice analytics
Contact center analytics is a complex concoction of various technologies, like speech analytics, that ensure your service division runs smoothly. Here are the features of voice analytics technology.
1. Speech recognition and conversion
Converting spoken words into text and vice-versa is foundational for documentation and system responses in contact centers.
Automatic Speech Recognition (ASR): ASR technology is designed to convert spoken language into written text. It uses algorithms trained on vast amounts of audio data to recognize patterns in speech.
Text-to-Speech (TTS): The inverse of ASR, TTS takes written text and converts it into speech. It's utilized when systems, like voicebots, need to communicate with users vocally.
Phonetic analysis: Phonetic analysis focuses on the study of phonemes, the smallest units of sound in a language. It helps identify and understand pronunciation patterns.
Word spotting: Word spotting technology enables the detection and localization of specific words or phrases within an audio recording, even in the absence of complete transcription.
2. Natural Language Understanding (NLU) and Processing
Dissecting and understanding human language nuances is pivotal for effective customer interactions.
Natural Language Processing: NLP is the intersection of computer science, artificial intelligence and linguistics. It essentially helps in analyzing customer queries and ensuring agents or automated systems respond accurately.
Syntax analysis: Breaks down sentences into grammatical components to understand their structure.
Semantic analysis: Focuses on understanding the meaning of language.
Pragmatic analysis: Considers context and implied meanings in communication.
Topic modeling: This identifies topics within a large volume of text. For voice analytics, this can reveal what subjects are commonly discussed.
Keyword spotting and event detection: Recognizes specific predetermined words or phrases in spoken language. Detected keywords can help categorize calls and trigger specific actions.
Let’s take an example.
Amidst a shopping spree, Allison struggles with her credit card, bewildered because she knows she's within her limit. As she contacts the call center, NLP discerns her distress.
Syntax analysis breaks down her specific problem statement, while semantic analysis zeroes in on the keyword "credit limit."
Pragmatic analysis catches Allisons's undertone of urgency. Topic modeling slots the conversation under "Credit Card Glitches."
Hearing the terms "trouble" and “won't allow," keyword spotting swiftly connects Allison to Leslie, the card specialist, who's equipped with insights to guide Allison back to her retail therapy.
3. Emotion and speaker analysis
Capturing the emotional tone and speaker identity enhances the personalization and quality of interactions. Sentiment analysis detects emotions in a caller's voice, allowing agents to adjust their approach.
Acoustic analysis: Evaluates the speaker's tone, pitch and speed to infer emotions.
Lexical analysis: Examines word choice to deduce sentiment.
Speaker diarization: Differentiates and segments different active speakers in a single audio source.
4. Data management and real-time analysis
As calls flow in and out, it's essential to process, summarize and retrieve information quickly.
Call summarization: Generates brief overviews capturing the essence of customer-agent conversations, aiding quick reviews.
