LetMeTalk vs Niki Talk

LetMeTalk is a free AAC talker app for arranging images into sentences and speaking the resulting messages. Its library contains more than 9,000 ARASAAC images. Users can create unlimited categories, add images, and take new photos with a device camera. Vocabulary profiles can be saved, kept in multiples on one device, switched between, and shared with other devices. The listing names support for English, Spanish, French, Italian, German, Chinese, Portuguese, Brazilian Portuguese, Dutch, Arabic, Russian, Polish, Bulgarian, Romanian, Galician, Catalan, and Basque. LetMeTalk can work without an internet connection or mobile contract. It is described as suitable for people with conditions including autism spectrum disorder, aphasia, speech apraxia, articulation or phonological disorder, ALS, MND, cerebral palsy, and Down syndrome. The app is listed for Android and iOS, but the Android version was removed from Google Play on December 15, 2021. Apple’s listing says privacy-practice details have not been provided.

Niki Talk is an augmentative and alternative communication app intended to help children with autism or disabilities that impair communication. With Niki Talk Designer, users can create custom boards and add pictograms and photos to a personalized album. Designer generates speech through text-to-speech in 31 languages, and the purchase page lists 70 voices. The Trial version lasts 30 days and limits an album to 30 pictures. The Full version costs €4,900, paid once and provides unlimited album pictures and access that never expires. Both plans list one user and unlimited downloads on iPad, iPhone, and Android. The app is also listed for Kindle; Designer can be used on PC, Mac, and iPad. To use an album on a device, users configure it with the same ID and password as Designer and enable album downloads. The maker says its apps do not collect or transmit personal or location data, use analytics, or include advertising. A separate app, Niki Agenda, supports daily or weekly scheduling, activity symbols, customizable pictograms, and token-based rewards.
