Talko 2 Eurorack
Description
Talko2 is a compact, DIY-friendly Eurorack speech module built on the same proven engine used across the Polaxis lineup.
In homage to Error Instruments, the glitch button is named Error, unlocking wild and unpredictable textures.
It speaks numbers, alphabets, phonemes, and classic phrase banks, all with real-time control over pitch, speed, and effects.
A 7-segment display shows the active bank or the selected effect.
Designed for experimental voices and robotic sound design, Talko2 is both a classic speech engine and a versatile creative 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 20 mA.
- Power: Standard Eurorack ±12 V supply through a 10-pin header.
- Width: 18 HP (approximately 91 mm).
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
