Marchex’s AI-Powered Speech Analytics Sets New Standard, Approaches Human Levels of Accuracy in Consumer to Business Conversations

Driven by investments in data science and deep learning technology,
Marchex delivers best-in-category insights on customer conversations

SEATTLE–(BUSINESS WIRE)–lt;a href=”” target=”_blank”gt;#marketinglt;/agt;–Marchex (NASDAQ: MCHX),
a leading provider of call analytics that drive, measure, and convert
callers into customers, today announced that is has reached a new
industry standard in automatic transcription accuracy for
consumer-to-business phone conversations, driven by enhancements to and
investments in its proprietary speech analytics solution.

Marchex’s speech recognition functionality was put to an independently
verified test against several other commercially-available solutions,
based on a series of factors to directly compare capabilities. Using the
same sample audio data from the business conversation domain, the test
measured the word error rate (WER) which tracks the number of words that
are inserted, deleted or substituted in order to discern overall
accuracy of a transcription. The internal
, which was verified by enterprise technology analyst
Frank Ohlhorst, found that:

  • Marchex achieved an overall WER of 8.4 percent, which is a 20
    percent improvement since 2017, and considerably better compared to
    other voice recognition systems.
  • Marchex’s speech analytics solution performed 38 percent more
    accurately than IBM Watson
    , 37 percent more accurately than Azure
    Cognitive Service API, 13 percent more accurately than Google Cloud
    Speech-to-Text API and more than 11 percent more accurately than
    Amazon Transcribe API.
  • Marchex speech analytics technology is nearing parity to human
    , which is roughly a 5 percent WER1.

For industries with a significant reliance on phone calls to drive
sales, such as the automotive, travel and home services industries,
AI-powered conversation analytics technology is critical to delivering
sales enhancing personalized solutions. Accuracy plays a significant
role in being able to automatically pinpoint the reason why a customer
is calling, the outcome of the conversation, and the ability to classify
calls in real-time.

“Marchex takes a multi-pronged approach to resolving the issues
associated with human to human interactions in the enterprise business
space,” said Frank Ohlhorst, technology analyst. “Processing accuracy is
a viable benchmark and Marchex was able to outperform other solutions,
especially where accuracy was concerned.”

Marchex invested in several key enhancements to its speech analytics
technology, including additional deep learning capabilities, which have
expanded both the accuracy and capacity of consumer-to-business
conversation analysis. In addition, Marchex has invested heavily in
internal resources, including the launch of the Marchex Innovation
Development (MIND) Lab and the addition of several new data scientists.
These investments represent Marchex’s ongoing dedication to lead and
innovate within the speech analytics sector.

“In recent months we’ve prioritized resources and targeted investments
to further advance our speech technology,” said William Li, vice
president of engineering at Marchex. “With our data science team leading
our MIND Lab, Marchex is delivering meaningful insights that help
businesses accelerate sales and deliver a better conversational
experience for their business.”
