Exploring TTS limitations user experience: What you need to know

3 min read

Text-to-Speech (TTS) technology has come a long way in recent years, providing a convenient way for people to listen to digital content. However, despite its advancements, TTS technology still has some limitations that can negatively impact the user experience. In this blog post, we will explore the various limitations of TTS technology and how they affect user experience.

Lack of Naturalness

One of the primary limitations of TTS technology is the lack of naturalness in the synthesized speech. While TTS systems have come a long way in terms of sounding more human-like, the prosody, intonation, and variability of human speech are still hard to replicate. As a result, synthesized speech can often sound robotic, stilted, or monotonous. This lack of naturalness can negatively impact the user experience, making it harder for users to engage with the content.

Limited Emotion and Expressiveness

TTS systems cannot yet replicate the full range of emotional and expressive qualities of human speech. While some systems can simulate emotions like anger, happiness, and sadness, they often lack the subtle nuances of human speech that convey more complex emotions. Since computers are not sensitive enough to context, they ignore emotions and feelings. Therefore, TTS has become a tool for announcements involving rules and regulations (court, police, customs, etc.). This limitation can make it harder for users to engage with content that requires a deeper understanding of emotion and nuance.

Difficulty with Accented or Non-Native Languages

Another limitation of TTS technology is its difficulty with pronouncing words in non-standard or non-native accents. TTS systems rely on pre-recorded audio samples to generate speech, which may not include all accents or dialects. As a result, TTS systems may mispronounce words or phrases, leading to inaccuracies or misinterpretations. This limitation can be especially challenging for users who speak non-native languages or have accents, making it harder for them to engage with the content.

Complex or Technical Vocabulary

TTS systems may also struggle with complex or technical vocabulary, such as medical jargon or scientific terms. TTS systems rely on a database of words and their associated pronunciations, which may not include all technical terms. As a result, TTS systems may mispronounce or misinterpret technical vocabulary, leading to confusion or inaccuracies. This limitation can make it harder for users to engage with content that requires a deeper understanding of technical language.

Limited Contextual Understanding

Finally, TTS systems may struggle with contextual understanding. While TTS systems rely on complex algorithms and language models to convert text to speech, they still need to understand the context and intent of the text entirely. Without a full understanding of the context, TTS systems may mispronounce or misinterpret words or phrases, leading to inaccuracies or confusion. This limitation can make it harder for users to engage with content that requires a deeper understanding of the context.

Conclusion

In conclusion, while TTS technology has come a long way in recent years, it still has some limitations that can negatively impact the user experience. These limitations include a lack of naturalness, limited emotion and expressiveness, difficulty with accented or non-native languages, complex or technical vocabulary, and limited contextual understanding.
