For some ten years Texas Instruments have been developing solid state speech technology with the result that speech can now be produced which faithfully preserves the character of the spoken voice including intonation, accent, dialect, and pitch. Linked to a microcomputer, words can be strung together to make complete phrases and sentences so that

voice communication between `computer` and human becomes possible. The uses of this project are far reaching and will be of benefit to almost anyone who uses it. The carefully selected word library has many applications in the home and industry, for telephone, burglar alarms, conversations, messages, games, electronic terms, studio control speaking clock, temperature indication, calendar, business coding, factory announcements, and accountancy. This month we shall present the complete building project which can be purchased as a kit and explain how to interface the WORDMAKER board to a microcomputer. Possible interface circuits are included and BASIC programs are also given. It has already been fully tested on the Sharp MZ-80K and Tangerine systems. Further details are provided later for other popular micros and we shall be following this article with additional information on the processes of speech synthesis employed, and readers` ideas for interfacing and use will be welcomed. The E and MM WORDMAKER Speech Synthesiser is based on the Texas Instruments Voice Synthesis Processor (VSP). This card can be interfaced to any computer system or used as an independent unit. The card comprises the Texas TMS 5100 Voice Synthesis Processor; a memory bank containing the vocabulary and an onboard amplifier. The synthesis method used is called Linear Predictive Coding (LPC). This is a technique developed by Texas which minimises the...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
