TTS stands for text-to-speech. It's an AI-assisted technology that converts written text into spoken words. TTS systems like Inworld's TTS API analyze the text and use synthesized voices to pronounce the words. TTS technology has applications in various fields, including video games, apps, customer service, content creation, chatbots, voice overs, and audiobooks. 

TTS technology varies in its capabilities, quality, fluency, accuracy, and more. Some TTS models sound more robotic while others have expressive voices that sound similar to a person speaking. TTS software can also take different amounts of time to output voices – from real time voice output to output that can take seconds to a minute to fully process. 

Inworld’s TTS model provides expressive voices.  

Using text-to-speech technology is easy. Here's a basic guide on how to use it:

Choose a TTS tool: There are various TTS tools available, both as software applications, online services, and APIs.

Input text: Once you have selected a TTS tool, you'll typically have an interface where you can input the text you want to convert to speech or an API that you can connect with your application architecture. You’ll then need to input text in the form of typing directly into a text box, uploading a document, or connecting your TTS to something like a large language model (LLM) or conversational AI model that’s generating text for you. 

Select voice and settings: Many TTS tools allow you to choose from different voices and adjust settings such as speed. Select the voice that you find most suitable and configure other settings according to your preferences.

Preview and adjust: Before generating the final output, it's a good idea to preview the speech to ensure it sounds natural and clear. Make any necessary adjustments to the settings if required.

Generate speech: Once you're satisfied with the settings, proceed to generate the speech. The TTS tool will convert the text into spoken words using the selected voice and settings.

Listen to the output: After the speech generation is complete, you can listen to the output to verify that it meets your expectations. If necessary, you can make further adjustments and regenerate the speech.

Integrate with your application or device (Optional): If you're using TTS for a specific application or device, you may need to integrate the generated speech into your system. Follow the instructions provided by the TTS tool for integration, which may involve using APIs or embedding code snippets.

By following these steps, you can effectively use text-to-speech technology to convert written text into spoken words for various purposes. Inwold simplifies this process with a TTS API and through an easy-to-use interface.

Inworld’s text-to-speech technology is used for a number of commercial use cases across various industries. Here are some examples:

Apps: TTS tools and applications are often integrated into apps to provide conversational AI or generative AI integrations with voice options. Use cases include assistants, reading apps, productivity apps, companion apps, and more. 

Video games and entertainment: TTS enhances multimedia and entertainment experiences by enabling the narration or voicing of characters in videos, video games, and interactive experiences like video games. Games can use TTS for both real-time dialogue or recording dialogue in advance. 

Content creation: Content creators, streamers, and podcasters often use TTS to add voiceovers, character dialogue, and immersive storytelling elements to their content.

Digital marketing and advertising: TTS is utilized in digital marketing and advertising campaigns to create audio advertisements, promotional videos, and branded content. Marketers leverage TTS to deliver targeted messages, engage audiences through audio channels, and enhance the reach and impact of their campaigns across online platforms and streaming services.

Customer service and support: Many businesses deploy TTS in their customer service and support operations. Automated phone systems, virtual assistants, and chatbots leverage TTS to provide information, answer customer queries, and guide users through self-service options. 

E-Learning and training: TTS technology is used to create audio versions of educational materials, textbooks, and training manuals. E-learning platforms, online courses, and educational apps incorporate TTS to facilitate auditory learning, cater to diverse learning styles, and accommodate learners with disabilities.

Overall, text-to-speech technology offers versatile solutions for businesses seeking to improve accessibility, streamline operations, enhance user experiences, and expand their reach. 

Speech synthesis, also known as text-to-speech (TTS), is the artificial production of human speech from written text. It involves the conversion of written words, sentences, or other linguistic units into spoken words using computer algorithms and synthesized voices.

Speech synthesis technologies, like Inworld Voices, analyze the input text to generate a corresponding sequence of speech sounds that closely resemble natural human speech. This process typically involves several stages, including text analysis, linguistic processing, and speech waveform generation.

Speech synthesis provides an effective means of converting written text into spoken format enhancing user experiences in interactive systems and enabling natural communication between humans and machines.

Speech synthesis, also known as text-to-speech (TTS), works by converting written text into spoken words. The process involves four steps: text analysis, linguistic processing, speech waveform generation, and voice synthesis. With Inworld Voices, these steps are taken implicitly in the model, simplifying the process for users of the product.   

Here's a simplified explanation of how speech synthesis works:

Text analysis: The first step involves analyzing the input text. This analysis helps the system understand the linguistic elements such as words, punctuation, and sentence structure. The system breaks down the text into manageable units for further processing.

Linguistic processing: Once the text is analyzed, linguistic rules and algorithms are applied to determine the pronunciation, intonation, and rhythm of each word and sentence. This step involves phonetic transcription, prosody modeling, and language-specific rules to ensure the synthesized speech sounds natural and intelligible.

Speech waveform generation: In this step, the system converts the synthesized linguistic information into an audio waveform that represents the spoken words. This waveform is generated by combining basic speech units, such as phonemes or diphones, and modulating parameters such as pitch, duration, and amplitude to produce human-like speech.

Voice synthesis: Speech synthesis systems often offer a variety of voices for users to choose from. These voices are created using recorded speech data from human speakers. Advanced techniques, such as concatenative synthesis or parametric synthesis, are used to create high-quality, natural-sounding voices that can be customized for different applications and languages.

Speech synthesis technology has a wide range of applications, including interactive voice response systems, virtual assistants, language learning tools, and more. It provides an effective means of converting written text into spoken format to facilitate communication and interaction between humans and machines.
