Improvements in speech recognition, text-to-speech and speaker verification technologies are set to give voice technology a significant boost, industry experts said yesterday.
According to research from US analyst firm Frost & Sullivan, the voice recognition market - worth $107m (£69m) in 2002 - will rocket to $1.24bn in 2009.
Frost & Sullivan said the adoption of open standards, particularly the acceptance of voice extensible mark-up language as the industry standard, had eased interoperability concerns and helped make the case for speech technologies for enterprise and carrier companies.
"As users experience increase in personal efficiency and job-related productivity, they are increasingly demanding a variety of speech applications, driving the introduction of speech applications and services by carriers seeking to differentiate themselves and grow revenues," said Elka Popova, analyst at Frost & Sullivan and the author of the report.
"Enterprises, too, are deploying speech solutions to improve customer service and increase sales."
But analyst Forrester warned that vendors need to ensure their products can be integrated with existing legacy-based systems to prevent customers worryng about integration costs.
Popova cited contact centre and customer service applications as offering the greatest growth potential, followed by unified messaging, speech-enabled auto-attendants and a variety of consumer applications.
