5. Ivona. Ivona has a free text-to-speech conversion service where you can copy paste the text to be converted and choose a voice from several available male and female voices. ivona’s text to speech reader lets you listen to the audio preview of the text before downloading it.
Since ivona mixes up free and paid conversion services in the same interface, it is a bit confusing for first time users of free conversion. Click on ‘Download’ and choose ‘Download without registration’ in the following window. There after choose the Free license, the desired recording format (mp3, ogg, A-law) and agree to their terms of use. Now the price comes down to $0.00 and you can downloadthe audio file by clicking on ‘ Buy Now’. The free version mixes background music to the converted audio file and also a short self-promo at the beginning and end of the track.
Though ivona has a not so easy to use navigation for free users, it is still worth a try, considering the advanced pronunciation improvement feature of it’s text to speech engine.
