Description
This module directly benefits from all these developments: a compact, DIY-friendly design, available both as a Eurorack module and as a standalone “Bricky” format inspired by Error Instruments. In homage, the glitch button has been renamed Error.
It speaks numbers, alphabets, phonemes, and classic phrase banks, with real-time pitch, speed, and effect controls.
A 7-segment display shows the active bank or the effect applied.
Designed for experimental voices and robotic textures,
Talko2 is both a classic speech engine and a sound-design tool.
Technical details
- Firmware update: UF2 drag-and-drop using a USB-C data cable.
- CV range – Sound, Speed, Pitch and FX: 0–3.3 V. Higher positive voltages are clipped at 3.3 V; inputs tolerate up to +10 V.
- Sound CV: Linearly selects the sounds within the active bank.
- Pitch CV: Controls speech pitch without calibrated musical scaling; does not follow 1 V/octave.
- Gate input: Positive gate signals; 0–5 V recommended. Accepts up to +10 V.
- Input protection: Resistors and clamping diodes protect the analogue CV inputs; the gate input uses a transistor buffer.
- Current consumption: Approximately 35 mA at 5 V.
- Power: 5–12 V DC through a 2.1 mm centre-positive barrel connector.
Quick Start
- Connect the audio output to your mixer or modular system.
- Patch a gate signal into the Gate input (or press the Gate button)
- Turn the Encoder to select a speech bank (shown on the 7-segment display).
- Use the Sound knob to pick the item (digit, letter, word, phoneme).
- Adjust Speed and Pitch to taste.
- Push the encoder and turn it to select an effect, and use the FX knob to adjust its depth
