History and Background of the DECtalk PC
The DECtalk PC was developed by Digital Equipment Corporation (DEC), a major player in the computing industry during the early '90s. Initially, DEC introduced the DTC-01, the predecessor to the DECtalk PC. The DTC-01 was a standalone device that could be connected to computers and terminals through a serial connection. However, the DECtalk PC took speech synthesis to the next level by integrating the technology directly into a PC.
The underlying speech synthesis system used by the DECtalk PC has several names, including DECtalk, DECvoice, MITalk, and KlattTalk. It was developed by Dennis Klatt, a renowned linguist and researcher in speech and hearing science at MIT. Klatt's work involved breaking down language into digital components, allowing for the generation of speech through synthesizers. The DECtalk PC utilized this technology, providing a range of voices for users to customize.
Speech Synthesis Technology
Speech synthesis, although not an obsolete concept even in the '90s, experienced a surge in popularity with the advent of AI assistants and modern speech technologies. However, the DECtalk PC brought speech synthesis directly into personal computers of that time period. Equipped with its own CPU and RAM, the DECtalk PC was a self-contained speech synthesis powerhouse. The technology utilized a combination of Intel X86-compatible CPUs, Texas Instrument chips, and one megabyte of RAM to generate speech.
The DECtalk PC featured nine preset voices, each with its own unique characteristics and quirks. Users could also customize their own voices using the available parameters. The DECtalk PC's ability to generate speech directly on the hardware level made it a fascinating piece of technology for its time.
Applications of the DECtalk PC
The DECtalk PC found a wide range of applications in various industries and settings. One notable area of use was in automated touch-tone phone systems, particularly the earlier model, the DTC-01, which included built-in telephony features. Banks, emergency services, weather radio stations, educational institutions, and libraries extensively utilized the DECtalk PC for its speech capabilities.
The DECtalk PC also played a crucial role in increasing accessibility for individuals with visual impairments and speech difficulties. It could be paired with screen reader software like JAWS or Outspoken, providing a way for users to Interact with computers using synthesized speech. Additionally, specialized systems like Dynovox offered a Simplified interface for individuals who needed assistive technology to communicate in public settings.
Accessibility Features
The DECtalk PC gained significant recognition for its contributions to accessibility. Its integration into screen reader software and partnerships with companies like Creative Labs expanded its accessibility features. For individuals with visual impairments, the DECtalk PC provided a means to audibly access text on computer screens. Its synthesized speech allowed users to interact with various applications, including word processors like WordPerfect.
Moreover, the DECtalk PC enabled individuals with speech difficulties to communicate effectively. By employing symbol-Based interfaces that represented common words and actions, specialized systems like the AWE32 Text Assist facilitated communication in real-world scenarios, such as ordering food. The DECtalk PC's impact on accessibility was profound, opening new avenues of interaction for those with diverse needs.
DECtalk PC in Popular Culture
The DECtalk PC left an indelible mark on popular culture, with its distinct robotic-sounding voices becoming iconic in various forms of media. Movie enthusiasts may recognize the DECtalk's voice from films like "Short Circuit," where the enemy robots used the DECtalk for speech synthesis. Another notable appearance was in "Back to the Future II," where futuristic scenes featured robotic voices speaking to the characters.
Perhaps the most famous application of the DECtalk technology was in the voice of the late Stephen Hawking. While Hawking's speech system initially utilized a product called Calltext 5010 by Speech Plus, which shared similarities with the DECtalk, it eventually evolved into a customized and distinct voice. However, DECtalk's influence on speech synthesis was undeniable, as it served as a foundation for many other voice technologies.
Setting up the DECtalk PC
To set up the DECtalk PC, You will need a compatible computer and the necessary software. The DECtalk PC card can be installed directly into a PC's expansion slot. Once installed, the DECtalk PC requires proper configuration, such as assigning the correct I/O address.
Additionally, connecting appropriate speakers to the DECtalk PC allows users to audibly hear the synthesized speech. The DECtalk PC supports mono output through a 3.5mm monospeaker jack. The configuration process may vary depending on the specific hardware and software setup.
Using the DECtalk PC
The DECtalk PC is primarily controlled through software, enabling users to generate speech based on text input. By utilizing the provided software, users can access various features of the DECtalk PC, including reading text files, issuing commands, and manipulating voices.
The software for the DECtalk PC includes programs that allow users to send text to the DECtalk PC for speech synthesis. Through this software, individuals can have the DECtalk PC Read aloud text files and even send text directly to the DECtalk PC through the COM or printer port.
Exploring the Different Voices
One of the highlights of the DECtalk PC is the availability of different voices. The DECtalk PC offers nine pre-set voices, each with its own personality and characteristics. Users can select voices like Paul, Betty, Huge Harry, Frank, Kid, Rita, Ursula, Val, and even Create their custom voice.
Each voice has its own unique qualities and nuances, making the DECtalk PC a versatile tool for speech synthesis. Experimenting with different voices can add an additional layer of fun and creativity to the DECtalk PC experience.
DECtalk PC Emulator and Additional Resources
