0:03:15 - (Daniel): A perfect use case for voice cloning. Right now, I only intend to use my cloned voice for this episode, not all podcast episodes, however, this was a perfect example of its usage. So listen to episode eleven of Making Sense of Technology in Multimedia and tell me what you think. Let's get to it. First up is understanding speech synthesis.
0:03:42 - (Daniel): Speech synthesis uses artificial intelligence algorithms to generate humanlike speech from written text. This technology has evolved significantly, progressing from robotic and monotonous voices to sophisticated and natural sounding speech patterns. Modern speech synthesis. AI software produces accurate and engaging vocal outputs using neural networks to analyze linguistic nuances and context. Early speech synthesis systems were rule based and relied on predefined sets of rules and phonetic components.
0:04:17 - (Daniel): These systems often produced robotic and monotonous voices lacking naturalness and expressiveness. Modern speech synthesis is primarily driven by neural networks especially deep learning models like Recurrent neural Networks, RNNs, convolutional neural Networks, CNNs and more recently, transformer based models like GPT Generative pretrained transformer. These neural networks are trained on large datasets of recorded human speech to learn the intricacies of natural speech patterns.
0:04:51 - (Daniel): Neural networks and speech synthesis systems analyze linguistic nuances such as phonetics and semantics. It allows them to generate speech that sounds humanlike and contextually appropriate. One of the significant advancements is the ability of modern TTS systems to understand and adapt to context. They consider sentence structure, punctuation and even the broader context of a conversation to generate more coherent and engaging speech.
0:05:24 - (Daniel): AIdriven TTS systems can now produce speech with different emotional tones, making them suitable for applications such as virtual assistants, customer service bots and audiobooks. This level of expressiveness enhances user engagement. Some advanced systems allow for voice cloning where someone can replicate a person's voice. I mentioned earlier why this episode uses my cloned voice. It can also be used for voice assistance or for preserving a loved one's voice for future interactions.
0:05:58 - (Daniel): AIdriven TTS can easily handle multiple languages and dialects, making them versatile for a global audience. They can also adapt to different accents and regional variations.

While AIdriven TTS has come a long way, challenges remain, such as generating perfect accents or avoiding biases in speech patterns. Ethical concerns related to deep fake voice manipulation and misinformation are also emerging issues. Speech synthesis technology has its roots in the mid 20th century, with early attempts resulting in robotic and unnatural voices.
0:07:06 - (Daniel): Despite its initial limitations, advancements in machine learning, deep learning, and neural networks have paved the way for remarkably realistic and humanlike speech synthesis. Speech synthesis is the technology that makes computers and machines talk like humans. It all began long ago when people tried to create devices that could imitate human speech. Early attempts used mechanical parts, but they sounded robotic and strange.
0:07:34 - (Daniel): In the 1930s and 1940s, a machine developed by Bell Labs called the Voter Voice Operating Demonstrator could make some speechlike sounds. A person had to operate it, and the results weren't natural. With the arrival of computers in the 1950s, scientists started using them to create electronic speech. These early computer programs made basic speech sounds but didn't sound like humans. In the 1960s, digital equipment corporation developed a technology called Deck Talk.
0:08:11 - (Daniel): It could talk better, but it was still pretty robotic. It used rules and algorithms to make speech. In the 1980s, things got better with concatenative synthesis. This method recorded small pieces of speech and put them together, making the speech sound more natural. A significant change happened in recent years when scientists used fancy computer models called neural networks to make speech. These models, like WaveNet and Tacotron, created voices that sound almost like real people.
0:08:45 - (Daniel): You can find speech synthesis in voice assistants like Siri and Alexa. Today, they use these advanced computer models to sound like real humans when they talk to us.
