These include British English, American English, Australian English, French, German, Italian, Spanish, Dutch, Danish and Russian. You can also store audio streams as MP3, Vorbis and PCM file formats, and there’s support for a range of international languages and dialects. To get text converted into speech, you just have to send it through the API, and it’ll send an audio stream straight back to your application. What’s great is that Polly is so easy to use. It sports an API that lets you easily integrate speech synthesis capabilities into ebooks, articles and other media. Developers can use the software to create speech-enabled products and apps.

Employing advanced deep learning techniques, the software turns text into lifelike speech. However, this just serves to confuse things further as the DPI (or PPI) value is only relevant (in practice) outside of the digital world.Alexa isn’t the only artificial intelligence tool created by tech giant Amazon as it also offers an intelligent text-to-speech system called Amazon Polly. A printer produces dots and a monitor produces pixels, so this name attempts to provide context when an image is digital. One other thing to note is that the DPI value of a digital image is sometimes also referred to as PPI (or Pixels Per Inch). You may change your DPI to any value you like. This tool supports JPG, PNG, TIF, BMP and ICO. However, it is much simpler to change the DPI of an image using the tool provided above. The printer would then output a larger number of dots for every inch, resulting in a sharper image.Īn image DPI value may be changed by opening the file inside MS (Microsoft) Paint, Adobe Photoshop or Illustrator. For example, a printing shop may request that a photo is submitted with 300 DPI rather than 72 DPI. The DPI value is read by some devices (such as printers) to determine how your image should be presented on a medium (such as paper). The actual quality (resolution) of the image (within the file itself) is not affected when its DPI value is adjusted. The DPI (dots per inch) of an image is simply metadata embedded inside the image (header). Your new image (with your chosen DPI) will instantly download to your device.
