One of his notable inventions is the "Speech Synthesized Telephone Answering Circuit." This circuit is designed for use with a telephone subscriber station. It utilizes a microprocessor control circuit to monitor a telephone line for a predetermined number of ringing signal bursts. A read-only memory contains a vocabulary of digitized words, allowing the microprocessor to answer the line and form a telephone answering message by retrieving selected words. This message is then converted to analog format and transmitted onto the calling telephone line.

Another significant patent is the "Speech Synthesized Time Announcement Circuit." This invention works with a telephone line control circuit. Upon detecting a predetermined number of ringing signal bursts or specific data patterns, a control microprocessor determines the current time of day. It forms a time-of-day message by retrieving selected digitized words from a read-only memory. The message is then converted to analog format and can be announced either over the telephone line or locally through a speaker.
