From input to output, the Speakjet voice chip seeks to recognize sound, from speech to new aural creations. Its architecture digitizes maps every sound collected by seven separate inputs. It routes those sounds for mixing prior to output. In the circuit world, however, hardware has limitations. This is why future editions of Speakjet are prime candidates for technological expansion. Designers can retain the existing architecture while upgrading Speakjet's components to suit the technical times.
Mathematical Sound Architecture (MSA)
Mathematics and architectural structures have been conceptually linked for centuries. Speakjet deploys Mathematical Sound Architecture (MSA), in which numbers represent sound. Although Magnevation, Speakjet's manufacturer, claims that MSA can map any sound, further depth of research could allow for expanded sound potential. If architecture makes structure of conceptual thinking, then MSA could become a numeric language which not only codes sound, but defines it. This idea is similar to developing more fidelity after the market introduction of sound on compact discs (CDs). One wonders: how could consumers use Speakjet as a sound creator? MSA programming expansion could help to answer that question.
Event Inputs
"Event Inputs provide a way to execute phrases, sound effects or control functions that have been pre-programmed," writes Magnevation. Each of Speakjet's seven sound event inputs can actually hold two sub-input signals. Given the expanding capacity of digital transfer technology, Magnevation could design future Speakjet chips to allow more sub-inputs for each of the seven event input channels. The schematic design would remain, but the input network capability could be expanded, just as Internet Service Providers (ISPs) are evolving ways and means for guiding more digital traffic through existing data infrastructure.
Synthesizer Power
Speakjet contains a five-channel synthesizer comprised of six oscillators, five mixers and Pulse Width Modulated (PWM) digital output. These components could be further developed. Although each mixer accepts and processes sound from multiple oscillators, the volume load of the mix is limited. While all mixes moderate volume, Speakjet mixers could be diversified to process more load itself, or provide enhanced mixing configurations. Magnevation's concept for mixer 5 as the "master," which blends all other mixes into one, is wise. However, mixer 5 applies a master volume level for PWM delivery from a 32-kHz square wave carrier. As technology continues to evolve, Speakjet can be upgraded to maintain the highest-integrity sound output.
Global Speech Recognition
Linguistic differences are based on how sounds are formed and pronounced in the mouth, so linguistic expansion may be a global frontier for Magnevation. Speakjet currently operates on speech recognition based on North American linguistic traits. The chip does allow for the production of any sound, but it synthesizes individual units of speech for word formation. Technological evolution, in this case, may be designed so that Speakjet could eventually recognize sound units, or phonemes, across global cultures. Admittedly, this would require a globalization of speech recognition. Once that issue was resolved, Speakjet would benefit from incorporating that capacity into its Mathematical Sound Architecture (MSA).
