Ce boitier d'extension, qui se connecte sur le port d'extension du TI-99/4 ou TI-99/4A, est l'un des tous premiers accessoires proposés par Texas Instruments. Avec Speech Synthesizer, l'ordinateur peut  parler!  Une prouesse pour l'époque.

Le vocabulaire résident se compose de 373 mots ou phrases. De nombreuses cartouches de jeux et éducatives l'utilisent. Le Speech Synthesizer sera sûrement l'extension la plus populaire des utilisateurs. Texas Instruments n'hésitant pas à la mettre en avant dans ces publicités.


La trappe située en façade restera inutilisée. Elle devait permettre l'installation de Speech ROM, des modules offrant des mots ou phrases supplémentaires. Une idée qui n'est pas sans rappeler les petits modules de la dictée magique, le célèbre jeu éducatif parlant de la firme texane.

 

 

Le Speech Synthesizer se compose de peu d'éléments:  Un processeur de synthèse vocale LPC TMS5220, deux ROM TMS6100 montées en piggy-back et un décodeur d'adresses 74LS138. Les ROM contiennent une bibliothèque de mots et phrases dont voici la liste:
