AI ( Ertificiell Intelligens) baserade TERA gör att du bland annat kan: - ringa vanliga telefonsamtal utan att ringa via tolk eller förmedlingstjänst. - vara nåbar i ditt jobb på ett vanligt telefonnummer tack vare att det finns ett Ring Direkt-nummer. - ringa trygghetstjänster som 1177 och 112. - ringa välfärdstjänster som kräver tonval. Det möjliggör kontakt med till exempel Vårdcentralen och Skatteverket. - anmäla dig till telefonkö för att sedan uppringd när motparten har tid. - använda porttelefon även om den styrs via telefon. - använda dig av tjänsterna för bildtelefoniförmedling i Sverige och Norge om du vill använda dig av en videotolk. Med TERA-Touch kan du ringa och ta emot samtal från vanlig telefon/mobiltelefon och få samtalet presenterat i text. Det motparten säger, får du både som ljud och omvandlat till text. Har du svårigheter med att tala kan du skriva. Det du skrivit omvandlas till en röst som motparten hör. Du kan naturligtvis använda din röst också som motparten kommer höra. Din motpart behöver inte ha denna app. De kan svara på (eller ringa upp dig med) deras vanliga telefon eller mobil. TERA innebär Komplett kommunikation. Alla kan nu på ett självklart sätt kommunicera med anhöriga, bekanta, affärskontakter och myndigheter. Komplett kommunikation ger trygghet och egenmakt. För att använda TERA-Touch behöver du ha konto hos T-Meeting. Sverige: Kontakta din förskrivare på ditt Landsting, din handläggare på Arbetsförmedlingen eller på Försäkringskassan för att få veta hur det går till. Norge: kontakta NAV Hjelpemiddelsentral.
