Text to Speech

What is text-to-speech?

Text-to-speech (TTS) is a cutting-edge technology that helps convert text formats into voice outputs. Also known as speech synthesis, text-to-speech software is an assistive technology that excellently interprets any form of text documents and webpages.

Businesses widely employ it to enhance user experience, increase engagement, and make the data more accessible. The advancement of artificial intelligence has further improved the experience by allowing more natural-sounding voices that often sound almost indistinguishable from authentic voices.

Types of text-to-speech software

There are different types of text-to-speech software available, each catering to specific needs and use cases. Here are some common types:

• Built-in text-to-speech: Several devices come with TTS tools preinstalled. This includes Chrome, digital tablets, smartphones, and desktop and laptop PCs. These built-in TTS tools cover read-aloud and dictation features.
• Text-to-speech API: This type of software provides an application programming interface (API) that allows developers to integrate TTS capabilities into their applications or websites. Developers and businesses who want to incorporate synthesized voices into their software products or services use it.
• Multilingual text-to-speech: Multilingual TTS software supports the conversion of text into spoken words in multiple languages. This software enables localized content creation and enhances the user experience for individuals who prefer consuming content in their native language. It is valuable for businesses operating in global markets or those catering to diverse linguistic audiences. 

Benefits of using text-to-speech software

Text-to-speech software offers several benefits that can make jobs easier and improve sales or profitability. Here are some key benefits:

• Time and resource optimization: TTS software automates the process of converting written text into spoken words, saving significant time and resources. Businesses can, thus, leverage the software to generate synthesized voices instantly instead of manually recording voiceovers or hiring voice actors.
• Customization and personalization: TTS tools provide extensive customization options, allowing businesses to tailor the synthesized voices to their needs. Customization features like volume, pitch, speed, and emotion enable enterprises to create a personalized and engaging user experience. 
• Enhanced accessibility and inclusivity: TTS solutions improve accessibility by converting written content into spoken words. This feature enables individuals with visual impairments or reading difficulties to access information more effectively.
  By making content accessible to a broader audience, businesses can increase their reach and create a more inclusive environment. This accessibility also extends to individuals who prefer audio-based learning or prefer listening to content while multitasking rather than reading it.

Impacts of using text-to-speech tools 

A company developing an e-learning platform, for instance, can utilize TTS tools to transform written course materials into spoken words, allowing learners to listen to the content instead of reading it. This feature makes the material more accessible, particularly for visually impaired individuals or those who prefer auditory learning.

Furthermore, TTS software enables businesses to modify the pronunciation of specific words, customize the accent of the voice, and even control the emotion conveyed by the synthesized speech.

For example, an interactive storytelling application can use TTS tools to bring characters to life with unique voices, accents, and emotional expressions, enhancing the immersive storytelling experience for the audience.

• Content creators and writers: Content creators and writers can utilize this software to proofread their written content by listening to the synthesized voice. This can help identify errors, inconsistencies, or awkward phrasings they may have missed during editing.
• Mobile app and game developers: Mobile app and game developers can utilize TTS software to enhance the audio experience within their applications. This software enables developers to add voice-based functionalities, such as voice commands or voice-activated features, making their applications or games more engaging and user-friendly.
  By incorporating synthesized voices for character dialogues, narrations, or in-game instructions, they can create immersive and interactive experiences for their users. 
• Customer support and call center representatives: Customer support and call center representatives can benefit from TTS software in their daily interactions. The software allows them to access written customer queries or support tickets and convert them into spoken words.
  This capability enables representatives to listen to the content and provide real-time assistance, improving response times. It also helps ensure accuracy and consistency in their responses, enhancing the overall customer experience and satisfaction.

Basic elements of text-to-speech software

The following are some core features within text-to-speech software that can help users add text-to-speech to their applications or business processes:

• Voice generation: TTS software allows users to generate a voice, typically allowing for some degree of customization, such as tone, style, and gender.
• Hard-coding pronunciation: Although TTS technology is advanced and can typically pronounce words properly, many tools allow users to customize how specific words are pronounced.

• Integration with existing applications or devices: TTS software that supports integration with existing applications or devices allows businesses to incorporate synthesized voices into their workflows seamlessly.

Text-to-speech best practices

In order to make text-to-speech work effectively, businesses can follow these best practices:

• Naturalness and intelligibility: One of the challenges with TTS software is achieving a balance between naturalness and intelligibility in the AI voice output. While advancements in neural networks have improved voice quality, some synthesized voices may still need the natural cadence, prosody, or pronunciation required for optimal user experience.
• Compliance requirements: Certain industries, such as healthcare or finance, have specific regulations for handling sensitive data. TTS software may encounter challenges in meeting these compliance requirements, especially when dealing with confidential or personal information.

Text-to-speech vs. speech-to-text

Text-to-speech technology providers differ from voice recognition or speech-to-text software as the latter transforms speech data into text, whereas TTS transforms text into spoken audio.
