Installation

1.Save the firmware file to an SD card with a name like “Aria.bin”.

2.Load it from the Code > Flash menu.

3.The firmware will be copied as “firmware.bin”, and the system will reboot.

4.The original firmware file remains on the SD card under its own name.

This process works for EMY, Mea, Kaiwa, Sino, and Vax, allowing easy switching between firmwares.

Main Menu

Vowel
Use the main switch to change the desired mode :

•Trigger Mode – When triggered by the gate, vowels play for their entire frame duration.

•Gate Mode – Vowels play only while the gate is high and stop when low.

•Continuous Mode – Vowels loop seamlessly, with transitions affected by frame and merge duration.

Parameters

• P1 – Sample Rate

• P2 – Master Pitch

• P3 – Frame Duration

•P4 – Merge Duration (smooth transitions between vowels)

• P5 – Noise Level

• Sound – Choose Vowel to play

Code

•Code Display – Shows the current firmware version.

•Calibration – Potentiometer calibration tool.

•Flasher – Firmware loader to select and install different firmware versions.

Demo

Read texts from the micro SD card in plain English.
The sound produced by S.A.M is a robotic, monotone voice with a slightly metallic quality.

The user can adjust the Pitch, Speed, Mouth, and Throat.

Note that the code is blocking, and the potentiometer positions are read during the pauses between utterances.
(only the Rate P1 can be used in real-time)

Installation

Save it on the SD card with a name like “SAM.bin,” and you can load it from the code>flash menu.
The same applies to the EMY, Mea, Kaiwa, Sino & Vax firmware so that you can switch from one to another within the main menu.

This function copies the firmware to “firmware.bin” and reboots the system.
It will delete the firmware.bin but keep the original firmware on the card with its own name.

 Demo

It generates speech from plain English or Chinese by reading files on the microSD card.

Sino Manual

Timing

Real-time
The various voice parameters are applied just before triggering the speech and are ineffective while speaking.
They are applied to the next utterance. The best is to fiddle a bit with the knobs for the desired effects.
While playing with the interface, the display shows the parameters changes.

MIDI

You can use a midi sequencer to store letters as MIDI notes. 

(C#6 is letter a) The speech starts when Sinovox receives the “.” character (MIDI note A#1). The space character is the MIDI note G#0

Pitch bend can be used to set the pitch from 0-10.

The MIDI clock is present on the Busy jack.

You can use a custom MIDI track in Ableton live to ease the process of “typing” text.

TMS5220/TMS5100 speech engine

• 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.

Technical Details

• 16 hp
• micro SD card reader to read the text or update the firmware
• Diode for reverse polarity protection on power lines
• Consumption : +12V 60mA / -12V 18 mA
• Cortex-M0 ARM processor
• All inputs: 100k impedance, 12-bit ADC.
• CV control designed for  0-5 V entries
• aux out signal 5V
• OLED display
• mikroBUS host
• Output level 8 Vpp
• A USB port for communication,  firmware updates, and USB keyboard  text entry

Use with a microcontroller

The hardware is compatible with the mikroBUS^TM standard, allowing rapid prototyping and easy integration into existing projects.

The onboard class-d amplifier can drive a small 8 ohms speaker.

This vox board was designed to be used with EMY and its appropriate firmware. (in this case, the audio signal is forwarded via the “PWM” pin – the jack is not used with Emy)

It can also be used in robots, toys, or any other retrocomputing speaking devices you may think of.

Thanks to the popular mikroBUS™, this board can be instantly connected to multiple different platforms like the Arduino, the STMT32 of the Clicker2.
The onboard amplifier is quite powerful and is just waiting for the speaker to be plugged in!

Breadboard Connection

Code

The code is available here

Text to Speech

The chip can string phonemes to produce quite realistic speech (although with a French accent). It can also sustain notes for a nice singing effect. Here is how the Arduino code looks like :

dire("/bonj+w_r");
delay(400);
dire("&l&kt€Ronik miwzik");
delay(400);
dire("i$ b+i-n ka+I+n -ma/$=+_ine");
delay(400);
dire("+?je pE ossi murmur*?");
delay(400);
dire("je suis un arduino qui parle"); // à corriger ;-)
delay(400);

You will find more information about the various phonemes and the prosodic markers in the following manual.
