Sampling the Intellivoice Voice Synthesis Module (Intellivision Chiptune) | Simon Hutchinson

video upload by Simon Hutchinson

"By request, I’m posting a free sample pack of recordings from the Intellivoice Voice Synthesis Module, including a simple Kontakt instrument that plays back these files.

Years ago, I made a synth using an arduino and a chip from an Intellivoice. Recently, I went into the closet and dug it out, and, following a couple repairs, recorded some samples for folks that are interested.

Get the sample pack:

The original Intellivoice Synth Video:"

"Demonstrating a synthesizer built from a chip from an old Intellivoice module (and played back inside the original case), MIDI-controlled through a keyboard or DAW.

Why? Games and gaming hardware are mass-produced devices with planned obsolescence and few serviceable parts. By "hacking" and customizing gaming hardware we regain personal ownership of these devices, and we can turn obsolete equipment into performable, expressive instruments."

1980s Echo text-to-speech synthesizer on the IMSAI 8080

video upload by df9999999999

"I recently was given a 1980s-era Echo PC voice synthesizer box with serial port interface. You simply send text to the both over the serial port and it speaks it. It uses the same chip as the old 1970s Texas Instruments speak and spell.

I figured out how to access TTY2 on the back of my newly completed IMSAI 8080 kit. Using XYBASIC, I wrote a program to speak various well known phrases from misbehaving computers featured in several scifi movies, including War Games, of course.

Accessing the TTY2 serial port on the back of the replica must be done by outputting a byte at a time to port 34. The default TTY2 baud rate was already 9600, matching that of the Echo PC. There is no handshaking. All must be coded manually. The Echo box has a very small character buffer and sends an XOFF command when the buffer fills and a XON when it clears. I check for those conditions in the BASIC program with some simple loops. Hardware handshaking on port 35 could be done, but the flag bit definitions are not well documented.

I set the cadence, pitch and inflection lower than default with a flat inflection that enhances understandability.

I also read the front panel switches to trigger the various phrases."

"Do you want to play a game?"

via Wikipedia
"The IMSAI 8080 was an early microcomputer released in late 1975, based on the Intel 8080 and later 8085 and S-100 bus.[1] It was a clone of its main competitor, the earlier MITS Altair 8800. The IMSAI is largely regarded as the first 'clone' microcomputer. The IMSAI machine ran a highly modified version of the CP/M operating system called IMDOS. It was developed, manufactured and sold by IMS Associates, Inc. (later renamed IMSAI Manufacturing Corp). In total, between 17,000 and 20,000 units were produced from 1975 to 1978."

Midi Narrator: A DIY midi controller Speech Synthesizer

video upload by Dbug's stuff

"I actually did film the construction of the device, but there were problems with the camera and the editing, so I decided to not publish the footage.

Here you can see the result of using the device 'stand alone', I did not manage to get it working reliably using the midi port, but I may have fudge a couple solders, I'll have to revisit that later.

The device was bought from"

Đorđe Balašević ( 11 May 1953 – 19 February 2021) was a Serbian and Yugoslav singer and songwriter, writer, poet and director. He began his career in the late 1970s as a member of the band Rani Mraz, transitioning after two albums to a solo career. He first gained mainstream prominence for writing Rani Mraz's hit "Računajte na nas" (Count on Us), which was often described as an anthem of a generation. Noted for his vivid lyricism and poetry, Balašević was also known for weaving political commentary into his songs and live performance.

Broadly supportive of South Slavic unity in late 1970s and early 1980s, in the lead up to the Yugoslav wars he began to criticise the authorities. During the Yugoslav wars, he became a prominent anti-war voice in the region, thanks to which he also became an UNHCR Goodwill Ambassador. Balašević was the first Serbian act to perform in Sarajevo following the siege of Sarajevo. Balašević became one of the most prominent critics of Slobodan Milošević's regime, at considerable personal risk. Djordje was a prolific singer and writer, he recorded 14 albums and 8 books during his career and has been characterised by media and commentators as "musical legend" and author of many "evergreen hits

Polaxis Terminal / Emy Speech Synthesizer

Note: This site contains affiliate links for which it may be compensated.

via this auction

You can find demos in previous posts here.

"Terminal is a standalone modular speech synthesizer containing Emy and a little PCB to provide power and extended connectivity.

It is powered via a USB connector. The casing allows adding any of the Vox modules inside just by removing four screws.

Terminal / EMY can be used in a CV-controlled environment or act as a MIDI instrument.

You can install the various firmware on the SD card before powering the device.

A pair of shunts allows the user to connect Terminal either as a MIDI USB unit or as a host for a USB keyboard for text entry. TRS jack MIDI Type B connector.

Emy is a versatile speech synthesizer that can host a hardware synthesizer on its back via a mikroBUS port. This port allows transforming Emy in a matter of a minute. TMS5220/TMS5100 / TMC0281 (Speak & Spell) included.

LPC data are read from the SD card so an infinite vocabulary can be loaded

Sound and vocabulary can be produced by concatenating allophones and prosody markers from the text file to affect rate, duration, and pitch. No limits here!

The OLED crisp display allows browsing amongst the files and the lines within files to pick the sound the user wants to generate.

Speech rendering can be tweaked in real-time to affect, rate, stretch, bend, pitch, and energy.

All the potentiometers have CV entries attached to them

Emy produces sounds in 3 major modes: Speech, Repeat, and VCO.

In Speech mode, the speech starts with a gate signal and is completed before waiting for a new gate signal. The speech has priority.

In Repeat mode, the speech starts and stops with the gate signal going high or low.

The gate has the priority, and the speech repeats while the gate is high. This mode is handy to create crazy rhythms.

In VCO mode, the LPC engine loops while the gate is high, producing steady notes."

SpeakJet first test

video upload by Polaxis

"Working on a new prototype: Speakjet vox, hosting the almost vintage chip of the same name. Here hosted inside the Terminal. I am playing with different modes: priority to the gate, priority to speech, and queuing phonemes. While queuing phonemes, the chip it triggering the snare when the buffer is half full, giving a nice feel to the beat"

Also see this post with Speakjet on Emy in 2018. The chip was also featured in the FLAME Talking MIDI Talking synth. You can find SpeakJet posts here.

1. Mea MIDI
Mea vox now behaves as an external MIDI instrument :
- MIDI note assigned to 39 phonemes.
- Velocity and Pitch bend supported.
- Can hold the note for singing effect.

I renamed the notes with Ableton Live MIDI Effects rack to help in sequencing phonemes by their sound. It is very easy to build a sequence!
2. Mea numbers

The Making of a TRS-80 Voice Synthesizer - Talker/80

Published on Mar 14, 2020 Michael Wessel

via Michael Wessel, who brought us the Speak&SID:

"New dimensions in voice synthesis for the iconic Trinity computer from 1977!

Talker/80 is a new speech (voice) synthesizer for the TRS-80 Model 1. It offers DECtalk-based natural sounding speech, and can emulate the "official" TRS Voice Synthesizer as well as the VS-100 Alpha Products voice synthesizer. The original software runs without changes / patches. Both the VS-100 and the TRS Voice Synthesizer utilized the Votrax SC-01 speech chip. The SC-01 is "emulated" by means of DECtalk here (phoneme mapping).

Everything is open source, including the firmware sources and Gerbers:"

FLAME Midi Talking Synthesizer w/ Joysticks

Note: This site contains affiliate links for which it may be compensated.

via this auction

"Includes original box, 2 original manuals and 4 different ac adapters for different types of worldwide voltage...

"The FLAME MIDI TALKING SYNTH is a small-sized MIDI-controlled sound module based on the analogue Speakjet ™ chip, produced by the U.S. company Magnevation LLC. Originally designed for basic artificially generated speech output in American English tongue it was then refined and further developed as an 8-bit sound module with speech-like sounds and synthetic robot voices as well as beeps, alarms, noise and retro-style sci-fi sounds. Due to the structure of the Speakjet ™ (with its complex sound synthesizer, preset sounds and serial interface) it offers an impressive range of possibilities. It contains 72 speech elements (allophones), 43 sound effects, and 12 DTM touch tones. The idea was to create sounds, patterns and sequences in the 8-bit style of the 80s or other retro sounds for making music instead of just simulating speech. Most allophones can be tuned and used tonally. The FLAME MIDI TALKING SYNTH contains two Speakjet ™ chips to produce a richer and more complex tonal variety as well as generating a pseudo stereo effect.

Since the Speakjet ™ has not originally been laid out for the purpose of making music it is actually not fully controllable via MIDI input, i.e.: once sounds are triggered they cannot be directly stopped by Note Off messages from a MIDI keyboard or a sequencer. Thus a MIDI-controlled audio tremolo has been implemented in the FLAME MIDI TALKING SYNTH virtually allowing MIDI control and enabling an easier integration into a MIDI setup. The FLAME MIDI TALKING SYNTH lets you play back preset words in its EXPANDER mode via an external MIDI keyboard or a sequencer. In addition you can use the FLAME MIDI TALKING SYNTH as a stand-alone MIDI controller since all controls and joysticks send MIDI control/change data to the MIDI-OUT connector.

The internal sound is generated by the two independently controlled Speakjet ™ chips. Each of them provides a mono audio output (32 kHz PWM output) through a 6.3 mm stereo socket. The right audio channel is assigned to chip A, the left channel to chip B. An insert Y cable splits both channels into two mono audio outputs, allowing you to position the channels individually within the stereo sound field with any external mixing device. The sound level ratio of both chips can be adjusted with the MIX control. An equal sound level is obtained by turning the MIX control to the cente5r position. All functions are clearly visible on the front panel with the start/ stop /MIDI-sync/ tempo functions on the upper right-hand corner, sound/ tremolo/ scale/ note/ pitch and random functions in the middle. The HOLD-switches are used to freeze the position of the joysticks. The REC-switches are used to play back the recorded movements of the joysticks. You can switch between the modes SEQUENCER (SEQ) and EXPANDER (EXP) with the switch in the middle of the panel."
