Parallax 30016 Emic 2 Text-to-Speech Module

The Parallax 30016 Emic 2 Text-to-Speech Module is a sophisticated speech synthesis device that converts digital text input into natural-sounding human speech output, utilizing advanced phonetic algorithms and multiple voice profiles. Professional developers, roboticists, and embedded systems engineers integrate this module into projects requiring voice feedback, accessibility features, and interactive audio interfaces without investing in complex audio processing infrastructure. This module solves the critical challenge of adding intelligent voice communication to microcontroller-based systems while maintaining minimal power consumption and compact form factor.

Product Overview

The Emic 2 operates through a serial communication protocol, accepting ASCII text strings from microcontrollers like Arduino, Propeller, or PIC platforms and converting them into audible speech in real-time. The module features a built-in amplifier capable of driving 8-ohm speakers directly, eliminating the need for external audio amplification stages. It employs Epson S1V30120 speech synthesis chipset technology combined with Parallax's optimized firmware, delivering clear articulation across multiple languages and adjustable speech parameters including pitch, rate, and volume. The device operates on 5V DC power with typical current draw of 150mA during active speech synthesis and minimal standby consumption, making it ideal for battery-powered robotics and portable applications.

What distinguishes the Emic 2 is its extensive phonetic control capability, allowing developers to fine-tune pronunciation through PHONEME commands alongside standard text input. The module includes onboard speaker amplification rated at 1 watt, eliminating external amplifier requirements for standard applications. Its robust error handling and feedback mechanisms provide real-time status reporting, enabling developers to synchronize visual displays or mechanical actions with speech output. The serial interface operates at 9600 baud by default with configurable rates up to 115200 baud, ensuring compatibility with legacy and modern microcontroller platforms.

How to Use

Begin by connecting the Emic 2 module to your microcontroller platform using a simple three-wire serial connection: TX pin to microcontroller RX, RX pin to microcontroller TX, and ground to common ground. Apply 5V DC power to the module and connect an 8-ohm speaker to the onboard audio output terminals. Configure your microcontroller's serial port to 9600 baud (8 data bits, 1 stop bit, no parity) and send text commands prefixed with the colon character, such as ":Hello World" to synthesize speech. The module will respond with a carriage return upon successful processing, allowing your code to detect completion and trigger subsequent actions or visual feedback.

For advanced applications, utilize the PHONEME command syntax to control pronunciation of specific words or implement multilingual content. Access voice selection through dedicated commands that persist across power cycles, and adjust speech parameters using dedicated rate and pitch commands before sending text. Monitor the status pin if your application requires real-time synchronization with speech output, or implement timeout-based polling of the serial interface for command completion detection. The module's serial buffer accommodates text strings up to approximately 1000 characters, enabling complex sentences and paragraphs to be synthesized without segmentation, though breaking large text blocks into manageable chunks improves responsiveness in interactive applications.

Frequently Asked Questions

Can the Emic 2 module synthesize text in languages other than English?

Yes, the Emic 2 supports English, Spanish, French, and German natively through firmware-based language selection. You can switch languages using dedicated serial commands, and the module applies proper phonetic rules, accent patterns, and pronunciation conventions for each language. For languages outside these four, you can use the PHONEME command to manually specify phonetic sequences, though this requires more detailed programming knowledge.

What is the maximum length of text that can be sent to the module in a single command?

The Emic 2's serial buffer can handle text strings up to approximately 1000 characters in length. For longer passages, it is recommended to break text into logical segments separated by brief pauses, which also improves the naturalness of speech output and allows better synchronization with visual elements or mechanical actions in your project.

Can I control the speech rate and pitch independently for different voice profiles?

Yes, the Emic 2 allows independent control of speech rate (adjustable from 75 to 300 words per minute) and pitch parameters for each voice profile. These settings can be configured before sending text and will persist until explicitly changed. This enables you to create varied vocal expressions within a single project, such as different character voices or emphasis patterns for different types of announcements.

Does the module require an external amplifier, or can it drive speakers directly?

The Emic 2 includes an integrated 1-watt amplifier that can drive 8-ohm speakers directly without external amplification. This onboard amplifier eliminates the need for additional audio circuitry in most applications. For applications requiring higher output power or multiple speakers, external amplification can be connected to the module's audio output terminals.

What microcontroller platforms are compatible with the Emic 2 module?

The Emic 2 communicates via standard RS-232 serial protocol, making it compatible with virtually any microcontroller platform that supports serial communication, including Arduino, Propeller, PIC, ARM Cortex-M, and Raspberry Pi (with appropriate serial interface). The module operates at 5V logic levels, so ensure your microcontroller uses 5V serial or include appropriate level-shifting circuitry if using 3.3V platforms.
