Project Background

Delacon develops leading telecommunication technology solutions and specialise in telecommunications and cloud-based SaaS (Software as a Services).  They are an industry leader in call tracking and are the only Google Analytics Certified Partner in the world that does Call Tracking. Delacon currently identify online marketing channels and AdWords keywords that yield high value phone sales then optimise and refine campaigns to deliver more high value phone calls. Delacon can then automatically capture data into a client CRM to see the user journey from online to phone sale. One such method of data capture uses a third party transcribing voice to text module.

Delacon’s aim is to continue development of a speech analytics module, which is able to analyse the transcribed call data (already speech converted to data) and produce reporting of:
