8. CONCLUSION




In this thesis, the objectives were to investigate the field of voice imitation and speech processing methods utilizing deep learning. concentrated mainly on developing a vocal mimicking method using CNNs, RNNs, and GANs. Throughout the research, several important aspects were addressed connected to voice cloning using the Tortoise TTS library.

Firstly, the importance of preprocessing the voice data was discussed, particularly when dealing with non-native speakers. emphasized the challenges associated with capturing the unique characteristics of non-native speakers and emphasized the need to adjust the voice data to ensure it is appropriate for the intended target audience. These modifications involve considering factors like accent, pronunciation patterns, and speech characteristics to produce a more natural and convincing voice output.

Then, an in-depth investigation was conducted into the functionality of the Tortoise TTS library and its capacity to generate speech with replicated voices. The library demonstrated impressive voice quality, but concerns were raised regarding its slow inference or generation speed. To remedy this, an enhanced version of the Tortoise TTS model was introduced.

For the purpose of validating the accuracy and authenticity of the voice cloning process, a method was used to compare the MFCC (Mel Frequency Cepstral Coefficients) features of the generated voice with one of the original voice samples. By utilizing cosine similarity, similarities between the voices were assessed through the calculation of a similarity score. To determine if the voices belonged to the same speaker, a threshold value of 0.8 was set, with greater scores indicating a closer match.

Throughout the study, a combination of quantitative and subjective indicators was employed to evaluate the efficacy of the proposed vocal mimicking method. The precision and genuineness of the generated speech were contrasted with those achieved by existing voice-mimicking techniques. This comprehensive evaluation enabled an analysis of the method's performance and a recognition of its strengths and limitations.

In conclusion, significant strides have been made in the field of voice cloning via the development of a deep learning-based vocal mimicking approach. The challenges associated with non-native speakers were effectively dealt with, Additionally, a validation approach based on MFCC comparison was successfully implemented. The findings from this research contribute to the current reservoir of knowledge in voice imitation and speech processing, and they highlight the possibility for further advancements and future research in this area.
