And with rapid advancements in the field, the technology no longer requires large volumes of voice samples or even professional equipment to function properly. These generators are also widely used in gaming, branding, animation, voice assistant development, audiobooks, and much more. TTS generators are used in a variety of ways, including as an assistive technology for people with learning difficulties, and by businesses and creators as a voiceover. Text to speech is a speech synthesis application that processes text and reads it out loud like a human. Installation of the data will happen automatically once the download completes.The rise of artificial intelligence (AI) has led to a wide range of incredible text to speech (TTS) generators and tools. If not, we need to let the user know to install the data that's required for the device to become a multi-lingual talking machine! Downloading and installing the data is accomplished by firing off the ACTION_INSTALL_TTS_DATA intent, which will take the user to Android Market, and will let her/him initiate the download. StartActivityForResult(checkIntent, MY_DATA_CHECK_CODE) Ī successful check will be marked by a CHECK_VOICE_DATA_PASS result code, indicating this device is ready to speak, after the creation of our object. So upon creating your activity, a good first step is to check for the presence of the TTS resources with the corresponding intent: Intent checkIntent = new Intent() ĬtAction(_CHECK_TTS_DATA) If a user wants to install those resources, the TTS API enables an application to query the platform for the availability of language files and can initiate their download and installation. So the voice and dictionary are language-specific resources that need to be loaded before the engine can start to speak.Īlthough all Android-powered devices that support the TTS functionality ship with the engine, some devices have limited storage and may lack the language-specific resource files.
The TTS engine needs to know which language to speak, as a word like "Paris", for example, is pronounced differently in French and English.
Also, depending on which side of the Atlantic you are on, American and British accents for English are both supported. The TTS engine that ships with the Android platform supports a number of languages: English, French, German, Italian and Spanish. Languages and resources About the TTS resources We will then show how to make your Android application talk and how to configure the way it speaks. Also known as "speech synthesis", TTS enables your Android device to "speak" text of different languages.īefore we explain how to use the TTS API itself, let's first review a few aspects of the engine that will be important to your TTS-enabled application. We've introduced a new feature in version 1.6 of the Android platform: Text-To-Speech (TTS).
