What is Text-to-Speech?

Text-to-Speech (TTS) software is an innovative technology that transforms written text into audible speech. This assistive technology, sometimes referred to as \"read aloud\" technology, is invaluable for creating accessible content for individuals who have difficulties with reading. It's also a practical tool that enhances productivity in the workplace, assists in proofreading by vocalizing written work, and serves as a means for generating voice-overs for various video content. TTS is beneficial for kids who struggle with reading, as it helps with writing, editing, and maintaining focus on comprehension. The technology supports a wide range of digital devices, can read different text files, and even online web pages through computer-generated voices.

As a service, TTS utilizes Google's advanced AI technologies, including an API that converts text into natural-sounding speech with high fidelity. It offers a rich selection of voices, with over 380 options in more than 50 languages and variants, and includes both Neural2 and Studio voices. Neural2 voices are particularly sophisticated, based on the latest research and capable of delivering a custom voice model through Custom Voice. This service supports the Speech Synthesis Markup Language (SSML), which allows for the customization of speech, adding pauses, and formatting numbers, dates, and times for more natural pronunciation. TTS service is versatile, supporting multiple audio formats, and it is accessible through both REST and gRPC APIs. The service's pricing model is based on the volume of characters synthesized into audio each month.

TTS technology offers a variety of applications, from assisting kids with learning disabilities to aiding adults in various tasks. It is known for its compatibility with nearly all personal digital devices and its ability to read all types of text files, including those from images using Optical Character Recognition (OCR). TTS tools often come with features that highlight words as they are read aloud, creating a multisensory experience that improves word recognition, attention, and memory retention. By facilitating a focus on comprehension rather than decoding, TTS technology helps increase engagement with reading assignments. Moreover, it plays a significant role in helping users recognize and correct errors in their writing. TTS is likened to audiobooks in its utility and is widely available through various mediums, including online platforms, apps, Chrome tools, software programs, and even at schools, often at no cost.

TTS Plugins for Excel

Additionally, the Speak Cells tool can be integrated with Windows text-to-speech functions to enhance its capabilities.

Commands for Text-to-Speech

In Excel versions 2007 and 2003, text-to-speech commands can be utilized by navigating to Speech on the Tools menu. This functionality allows for a hands-free experience when reviewing data. Furthermore, the tool can be combined with the Speak On Enter command, which will prompt Excel to read the cell content only after the Enter key is pressed following a cell selection.
