Editing Festival Speech Synthesis System (1997) (section)

== LLM Reviews ==
We used Chat GPT developed by OpenAI to improve content quality and make up for the shortcomings. We let GPT act as a professor, speech synthesis researcher, the person who wants to jump into this field and the person who doesn’t have a background in speech synthesis. Generally, we got a great feedback from GPT. According to the general feedback from GPT, the content of our wiki page is informative and well-structured, providing a reasonably comprehensive and insightful overview of Festival Speech Synthesis System, including its historical context, key innovations, impacts on the field of speech technology, real-life applications, and future research directions. However, we were mindful that GPT was designed to give relatively good comments. Therefore we were careful to take what we could from it and not what we wouldn't. 

The prompts we raised and the corresponding improvement approaches provided by GPT are as follows: 

# '''Act as an voice technology professor and review this website, grade from 1-100 : 92'''
#* We let chat gpt as a professor to expect what grade we are getting and want to get a feedback from the person who has a professional background. We got a generally good feedback and several points for improvement from chat gpt as it always is. One of the improvement point we got is ''"You present a direction for future research, acknowledging the need for more voices in various languages and dialects. However, the section could benefit from more details on the specific areas of potential research".'' We respect the opinion that this needs to be improved, but we agree with the point that this may be off topic, so we did not change the contents.
# '''If you were a speech synthesis researcher, please evaluate the wiki page in terms of speech synthesis, and give us the feedback, which part can we improve?'''
#* The reason for the GPT review from the standpoint of a speech synthesis specialist is to ensure precise terminology, thorough historical context, and comprehensive coverage of technological advancements in the field.
#* Language Clarity: To ensure accessibility for a broader audience, consider simplifying complex technical terms and concepts, and provide explanations where necessary. We agree on this improvement point, thus we reviewed the whole content and tried to use a clear and concise language in order to enhance the overall comprehensibility of the content.
#* Inclusion of Recent Developments: Continuously update the page to include recent advancements in speech synthesis technology, such as the integration of neural network-based TTS and the latest developments in the commercial TTS services sector. Providing a section dedicated to recent developments can help readers grasp the current state and trends of the field more effectively.
# '''If you have some voice background and want to jump into the speech synthesis, does it help you? Any suggestions?'''
#* We let GPT be as students like us, who already have had rough knowledge about speech synthesis, and try to find out whether this wiki page is helpful and provide suggestions.
#* Technical Details: Adding more technical details about the inner workings of Festival Speech Synthesis, including the algorithms and models it employs, would be beneficial. This would help students grasp the core technology behind this system. According to the feedback from GPT, we add more technical details and information in key innovation part.
#* Demonstrations: Including practical demonstrations or examples of how Festival is used for text-to-speech conversion would be valuable. This could involve audio samples or step-by-step walkthroughs of the process. Challenges and Solutions: Discussing specific challenges in speech synthesis and how Festival addresses them would provide a deeper insight. For example, addressing the issue of diphthongs using the unit selection algorithm.
#'''If you didn’t know about speech synthesis before, will you have a comprehensive understanding after reading this wiki page? Which part do you think needs to be explained more clearly and understandably?'''
#*The reason for the GPT review from the viewpoint of a non-professional is to make sure this wiki page can assist individuals interested in voice technology, especially those with limited prior knowledge, in acquiring knowledge more effectively.
#*Enhancing Clarity with Examples: Incorporating additional real-world illustrations and simplifying technical descriptions can enhance the content's accessibility to a wider audience, particularly those who lack familiarity with speech synthesis and related technologies. In response to this feedback, we have heeded the suggestion and enriched the "Impacts" section with more detailed explanations for improved comprehension.
