The resulting E-speak 3.14 release in April 2000 was substantially different from the Client Utility, but it did retain many of its features. HP abandoned all its middleware products, including e-speak, in May 2001. At that time, five companies were using e-speak as a critical component of their businesses.

Other publications of parts of the Client Utility architecture are
