Feature Deep Dive

Voice Recognition

Voice Recognition monitoring uses audio analysis to verify the content of what is spoken during monitored calls. Rather than simply confirming a call was answered, PNM actively listens to the audio and checks for the presence of specific keywords, phrases, or audio patterns that indicate the call is proceeding correctly.

This capability is essential for validating IVR audio content, detecting when wrong recordings are played, confirming that agents are delivering required disclosures, and verifying that automated voice systems are functioning as designed. It adds a layer of content verification that pure connectivity monitoring cannot provide.

Everything You Need

A complete toolkit designed to give you full visibility and control over your phone line performance.

Keyword Detection

Define lists of keywords and phrases that must be present in call audio. PNM alerts you when expected words are missing or unexpected content is detected.

Audio Pattern Matching

Compare received call audio against reference recordings to detect when wrong messages are playing, audio quality has degraded, or content has changed.

IVR Audio Validation

Verify that your IVR system is playing the correct audio prompts at each step. Detect when recordings have been accidentally replaced or corrupted.

Multi-Language Support

Monitor calls in multiple languages. Configure separate keyword lists and reference recordings for each language your IVR system supports.

Compliance Verification

Confirm that required legal disclosures, regulatory statements, and compliance messages are present in every monitored call.

Content Change Alerts

Receive immediate alerts when audio content changes unexpectedly — whether from a system update, configuration error, or unauthorized modification.

Detection Analytics

Track keyword detection rates, audio match scores, and content anomalies over time to identify patterns and recurring issues.

Response Validation

Verify that voice-activated IVR systems correctly recognize and respond to spoken commands — testing the full voice interaction loop.

Simple Setup

How It Works

Simple to set up, powerful in practice. Get started in minutes with no hardware required.
01

Configure Detection Rules

Define the keywords, phrases, or reference audio patterns that PNM should detect or match during monitored calls.

02

PNM Places & Records the Call

PNM dials your number, navigates the call flow, and records the full audio of what is played during the call.

03

Audio Is Analyzed

The recorded audio is analyzed for the presence of configured keywords and compared against reference recordings for pattern matching.

04

Results & Alerts

Detection results are logged with timestamps. If expected content is missing or unexpected content is found, alerts are sent immediately.

Frequently Asked Questions

What types of audio content can PNM detect?
PNM can detect specific keywords and phrases spoken during a call, match audio patterns against reference recordings, and identify the presence or absence of expected audio content.
Does voice recognition work with all languages?
PNM supports multi-language audio analysis. You can configure separate detection rules and reference recordings for each language your system supports.
Can PNM verify that a voice IVR correctly understands spoken commands?
Yes. PNM can play pre-recorded audio responses to voice-activated IVR systems and verify that the system correctly recognizes and responds to the spoken input.
How accurate is the keyword detection?
Detection accuracy depends on audio quality and the specificity of configured keywords. PNM provides configurable detection thresholds to balance sensitivity and false positive rates.
Can I use voice recognition alongside IVR testing?
Yes. Voice Recognition and IVR System Testing can be combined in the same monitoring plan to validate both routing and audio content simultaneously.
