The Voder was demonstrated to the public at the [[wikipedia:1939_New_York_World's_Fair|1939 New York World's Fair]], attracting widespread attention and showcasing the possibilities of artificial speech production. It was a significant step towards public awareness and interest in the field of speech synthesis. Bell Labs also continued its research in this field, and nearly two decades later, in the 1960s, they created a robot that could sing<ref>Cox, C. (1967). The Alien Voice.

In fact, the structure of Voder showed how source-filter model can be applied artificially: other electric models back in the 1950s and 1960s used a filter to pass the electric source along and emulated the resonance of the vocal tract as well<ref>Traunmüller, H.

Ever since the 1970s, the automatic text-to-speech systems have commercialized speech synthesis. The first system was created by the team led by Noriko Umeda in Japan back in 1968<ref>Klatt, D (1987). "Review of text-to-speech conversion for English".
