Over 30 years of contact center experience. Pivotal participant in many large contact center design and migration efforts. Cisco UCCE and Avaya are the best examples. Lately lots of 3CX,FreePBX and Asterisk assignments. Almost every call center change or migration requires a new recording. All of the recordings can be in the same voice making for a better user experience. We have invented a new scenario that allows us to provide our clients a Google TTS methodology. If the client can provide the text, we can turn the recordings around in very short order. We can do English, Spanish and many other languages. This is a very exciting technology shift that allows us to make the new recordings in minutes at at a very affordable price.
