Here are some best free online SSML editors to get more natural text to speech. With the websites that I have added here, you can prepare text that you want to feed into some text to speech converters. The SSML editor of these websites let you configure speech parameters like voice, pitch, loudness, speed, breaks, emphasis, etc., to make the final audio sound more natural. In most of the SSML editors below, you can edit SSML in WYSIWYG manner too. You can also opt to start from scratch and then get the final SSML code to do whatever you want.
SSML stands for Speech Synthesis Markup Language and it helps to carry out a natural text to speech conversion. The default voices used in TTS doesn’t sound like natural unless you are using some popular and paid services like Amazon Polly. For TTS with any tool, you can use SSML to customize the speech and get natural sound. Here you basically use HTML like tags to specify breaks, pauses, low pitch, soft sound, loud sound, etc., like parameters to customize each and every line in your text that you want to convert to speech.
After creating the SSML, you can feed that into any TTS converter that supports SSML. A few months ago I wrote about Chrome extension which was using Google’s Cloud Text to Speech and there was SSML support. So, the SSML created here can be used in that extension and tools like that. After getting the audio, you are free to do what you want.
