Att använda teknik för att underlätta lärande, eller tekniskt förstärkt lärande som det även kallas, är en metod som idag tillämpas i allt större grad. I den här rapporten undersöks metoden med tekniken talsyntes. Syftet är att se om den har en påverkan på memoreringsförmågan vid läsning. Grunden för den här undersökningen är befintlig forskning som visar på att vår inlärningsprocess kan effektiviseras genom att vi använder flera sinnen istället för ett ensamt. Således borde även memoreringen förbättras. I den här rapporten undersöks alltså huruvida den medietekniska produkten talsyntes ger en påverkan på hur fakta memoreras hos studenter.  För att undersöka det här fick två grupper av studenter läsa en faktamässigt rik text. Den ena gruppen fick även samtidigt lyssna på textens innehåll med hjälp av en talsyntes. Efter att deltagarna tagit åt sig texten fick de svara på flervalsfrågor om innehållet för att se hur väl de memorerat texten. Samma test skickades sedan ut efter tio dagar för att undersöka hur väl deltagarna kom ihåg faktan efter en längre tid. Resultaten från enkäterna, det vill säga antal rätta svar för de båda grupperna från bägge omgångarna, analyserades sedan med hjälp av statistiska metoder, som ANOVA, för att se om det finns en påverkan av talsyntesen.  Resultaten tyder på att det inte finns någon signifikant påverkan av talsyntesen på förmågan att memorera fakta. Testerna visar att memoreringsförmågan överlag såg snarlik ut hos de båda deltagargrupperna. Däremot finns vissa frågor där gruppen som använde talsyntes hade noterbart fler antal rätt i jämförelse med dem som inte hade talsyntes. För vidare studier inom ämnet bör en undersökning göras i större omfång och under en längre tidsperiod för att få bättre mätningsresultat.
