Niki Talk vs TouchChat HD

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.

TouchChat HD is an AAC communication app for people who cannot rely on natural speech, including people with autism, Down syndrome, ALS, apraxia, or stroke. It creates words and messages that can be spoken through a built-in voice synthesizer or recorded audio. The WordPower edition adds AAC vocabularies developed by speech-language pathologist Nancy Inman. Pages, button layouts, messages, and symbols can be customized, with more than 45 button actions and nearly 40,000 SymbolStix symbols listed. Access options include touch, configurable switch scanning, adjustable button timing, gestures, and supported-device head tracking. Listed languages are English, Spanish, Canadian French, Arabic, Hebrew, and Mandarin, with language combinations supported. Text can be shared through social media, iMessage, or email. Vocabulary files support iTunes file sharing, Dropbox, and Google Drive, while backups can use iCloud, Google Drive, or Dropbox. It runs on iPhone, iPad, and compatible Mac computers.
