How Does Speech Analytics Work? 

Core Technologies

The core technologies behind speech analytics include the following.

• Automatic speech recognition: Converts spoken language into text.
• Natural language processing: Analyzes and interprets the meaning and context of the transcribed text.
• Machine learning algorithms: Identify patterns, trends and anomalies in the data they collect.

Process

Speech analytics typically follow these steps.

• Audio capture: Recording of conversations through various channels such as phone calls, video calls and face-to-face interactions.
• Transcription: Converting the audio recordings into text using automatic speech recognition.
• Embedding acoustic data: Pairing the acoustic data with the timings from the recognized transcript to capture how something is said.
• Text analysis: Applying NLP to understand the sentiment, keywords and context.
• Data analysis and visualization: Analyzing the combined data and presenting it in a user-friendly format, often through dashboards and reports, to derive business insights.

Features of Speech Analytics

The core feature of any speech analytics system is the speech-to-text engine or recognizer, which is responsible for converting spoken language into a text transcript.

This transcript is the foundation for building further analysis, allowing natural language processing and machine learning algorithms to process the content and context of the conversation.

Speech analytics is essentially text analytics applied to the recognized text of a conversation. It goes beyond mere text analysis, though, by incorporating conversation data such as pace, tone and volume, adding layers of context that provide a richer understanding of the interaction.

The outputs of speech analytics are multi-faceted and highly valuable to businesses, including the following.

• Transcripts: Accurate renderings of the spoken conversation into text form, which can be stored, searched and analyzed.
• Call scores: Evaluations based on targeted sentiments such as satisfaction, experience, participation, engagement, responsiveness, complexity and effort.
• Notable events: Key moments in the conversation, such as agreement, dissatisfaction or escalation, that require attention or action.
• Reasons for interaction: Insights into why the conversation took place, identifying the underlying motivations or issues.
• Topics and segments: Identification of the main topics discussed and the segmentation of the conversation into relevant parts for more focused analysis.

These features collectively allow businesses to extract actionable insights from spoken interactions, driving improvements in customer service, compliance and overall operational efficiency.

Limitations of Using Speech Analytics 

Technical Challenges

Implementing speech analytics can be technically challenging, requiring robust infrastructure and integration with existing systems. Ensuring the accuracy of transcriptions and interpretations, especially with diverse accents and languages, can also be difficult.

Privacy Concerns

The use of speech analytics raises privacy concerns, as it involves recording and analyzing customer interactions. Organizations must comply with data protection regulations and obtain necessary consent from customers. This is particularly important in industries where recording conversations is not a standard practice.

For instance, general contact centers that handle routine inquiries or sales transactions typically require a notification at the beginning of a call, informing the customer that calls may be monitored for quality assurance or similar purposes. This notice is a legal requirement in many jurisdictions to ensure transparency and obtain implicit consent for recording.

In contrast, certain types of contact centers, such as emergency services (e.g., 911 centers), may not require explicit consent to record interactions. These centers operate under different regulatory frameworks where the primary focus is on public safety, and recording is deemed essential for operational effectiveness.

Even in these cases, though, organizations must still adhere to relevant privacy laws and securely store recordings, accessed only by authorized personnel.
