Mastering IBM Watson Text to Speech API - A Comprehensive Guide

IBM Watson text to speech API is a powerful tool that allows developers to convert written text into natural-sounding audio in a variety of languages. The API is designed to be easy to use, with a simple interface that requires only an IBM Watson TTS API key to access. This key, which can be obtained from the IBM Cloud dashboard, is used to authenticate the user and provide access to the API's features. It's important to note that the IBM Watson TTS API key is a critical component of the API's security measures, ensuring that only authorized users can access the service.

While the IBM Watson text to speech API is a robust tool, it is not without its limitations. One of the most significant IBM Watson TTS API limitations is the number of characters that can be converted to speech in a single API call. This limit, which is set to ensure the stability and performance of the API, can be a challenge for developers working with large volumes of text. However, with careful planning and efficient use of the API's features, developers can work within these limitations to create high-quality, natural-sounding audio from text.

Another notable limitation of the IBM Watson text to speech API is the range of voices and languages it supports. While the API does offer a variety of voices and languages, it may not cover all the specific needs of every project. This limitation, however, is mitigated by the API's support for custom voice models, which allow developers to create and train their own voices for use with the API. This feature, while requiring additional work, provides a solution to one of the IBM Watson TTS API limitations and expands the potential applications of the API.

Authors: Xu Tan, Jiawei Chen, Haohe Liu, Jian Cong, Chen Zhang, Yanqing Liu, Xi Wang, Yichong Leng, Yuanhao Yi, Lei He, Frank Soong, Tao Qin, Sheng Zhao, Tie-Yan Liu

Organization: Cornell University's Electrical Engineering and Systems Science department

Subject: Audio and Speech Processing

Summary: In this paper, we answer these questions by first defining the human-level quality based on the statistical significance of subjective measure and introducing appropriate guidelines to judge it, and then developing a TTS system called NaturalSpeech that achieves human-level quality on a benchmark dataset. Specifically, we leverage a variational autoencoder (VAE) for end-to-end text to waveform generation, with several key modules to enhance the capacity of the prior from text and reduce the complexity of the posterior from speech, including phoneme pre-training, differentiable duration modeling, bidirectional prior/posterior modeling, and a memory mechanism in VAE. Experiment evaluations on popular LJSpeech dataset show that our proposed NaturalSpeech achieves -0.01 CMOS (comparative mean opinion score) to human recordings at the sentence level, with Wilcoxon signed rank test at p-level p >> 0.05, which demonstrates no statistically significant difference from human recordings for the first time on this dataset.

4. Novel NLP Methods for Improved Text-To-Speech Synthesis

Author: Sevinj Yolchuyeva

Organization: Université du Québec (Trois-Rivieres)

Subjects: Deep Learning, Machine Learning, Natural Language Processing (NLP), neural Text-To-Speech

Summary: The goal of this dissertation is to introduce novel NLP methods, which have a relation directly or indirectly to serve in improving TTS synthesis. These methods are also useful for automatic speech recognition (ASR) and dialogue systems. In this dissertation, covered are three different tasks: Grapheme-to-phoneme Conversion (G2P), Text Normalization and Intent Detection. These tasks are important for any TTS system explicitly or implicitly. As the first approach, convolutional neural networks (CNN) is investigated for G2P conversion. Proposed is a novel CNN-based sequence-to-sequence (seq2seq) architecture. This approach includes an end-to-end CNN G2P conversion with residual connections, furthermore, a model, which utilizes a convolutional neural network (with and without residual connections) as encoder and Bi-LSTM as a decoder. As the second approach, the application of the transformer architecture is investigated for G2P conversion and compared its performance with recurrent and convolutional neural network-based state-of-the-art approaches. Beside TTS systems, G2P conversion has also been widely adopted for other systems, such as computer-assisted language learning, automatic speech recognition, speech-to-speech machine translation systems, spoken term detection, spoken document retrieval. When using a standard TTS system to read messages, many problems arise due to phenomena in messages, e.g., usage of abbreviations, emoticons, informal capitalization and punctuation. These problems also exist in other domains, such as blogs, forums, social network websites, chat rooms, message boards, and communication between players in online video game chat systems. Normalization of the text addresses this challenge. Developed is a novel CNN-based model, and this model is evaluated on an open dataset. The performance of CNNs is compared with a variety of different Long Short-Term Memory (LSTM) and bi-directional LSTM (Bi-LSTM) architectures on the same dataset. Intent detection forms an integral component of such dialogue systems. For intent detection, develop is a novel models, which utilize end-to-end CNN architecture with residual connections and the combination of Bi-LSTM and Self-attention Network (SAN). These are also evaluated on various datasets.
