摘要： A text-to-speech conversion system that includes a first module to convert text into words, a second module to convert words into phonemes, a third module to map phonemes to sound units, and a storage unit to store speech representations for a library of sound units. The first, second, and third modules and the storage unit are implemented within a single integrated circuit to reduce size and cost. The system typically further includes a ROM to store the codes for the modules, a RAM to store the text and intermediate results, a processor to execute the codes for the modules, a control module to direct the operation of the first, second, and third modules. The storage unit may be implemented with a multi-level, non-volatile analog storage array and may be programmed with a new library of speech representations by a programming module.

摘要： An apparatus and method for achieving accurate temperature-invariant sampling frequencies in a device, such as, a multiple message non-volatile multilevel analog signal recording and playback system is described. An oscillator is used to generate an oscillation frequency. A bandgap voltage generator generates a zero temperature coefficient voltage reference (V(OTC)) that is independent of temperature. This V(OTC) is applied to the oscillator. A variable temperature coefficient voltage (V(TC)) that compensates for temperature coefficient variations of a resistor to which V(TC) is applied produces a stable oscillator current Iosc. Therefore, the stable oscillator current Iosc is likewise independent of the temperature coefficient variations of the resistor. The stable oscillator current Iosc is applied to the oscillator such that the oscillator generates a stable temperature-invariant oscillation frequency. A digital divider is used to digitally divide the stable oscillation frequency by a predetermined amount to produce an accurate temperature-invariant sampling frequency. A filter is then used to filter incoming signals utilizing a filter cutoff that tracks the sampling frequency.

摘要： A single chip, single or dual message multilevel analog signal recording and playback system is described. In one embodiment, the system comprises a record circuit, an analog storage array, a playback circuit, and a control circuit that independently controls signal storage segments and duration capability. The record circuit receives an audio signal and generates a filtered signal, which is stored in the analog storage array. The playback circuit is coupled to the storage array for retrieving the stored signal for playback. The system further includes a mixer circuit which receives an auxiliary signal and mixes the auxiliary signal with the stored signal during playback. The control circuit also features a novel audio, visual, and input/output functionality.
