Ofer Ronen, CEO of Tomato.ai, Led Google CCAI
Overview
Over 99% of human voice communications today remain untouched by generative AI solutions. But in the coming years new speech AI solutions will emerge that will enhance the bulk of global communications.
To date, speech AI technologies, which transform speech, have primarily been used by content creators, movie studios, and game developers to enhance voices for immersive experiences. Companies like ElevenLabs have achieved unicorn status by delivering AI-generated voices that sound increasingly natural, transforming creative industries. However, the potential impact of speech AI extends far beyond these initial applications. It holds the promise to forever change global communications, enhancing everyday voice interactions for billions of people.
Before we dive into the transformative opportunities, including ethical or technical challenges associated with speech AI, let’s first clarify what it actually is. Simply put, speech AI involves feeding spoken language into an AI system, which then transforms the speech in various ways, such as changing the voice, softening the accent, or translating it to another language.
Solutions Landscape
Currently, the majority of speech AI applications are non-real-time, requiring several seconds to generate an output. This lag makes them more suitable for recorded content, such as video or audio production, but impractical for live, back-and-forth conversations where fluid unscripted communication demands near-instantaneous responses. In real-time scenarios, sub-second latency is crucial for maintaining the natural flow of dialogue, and the current limitations make existing solutions less ideal for these interactions.
Moreover, most speech AI solutions available today function as voice changers. While these tools have some use cases, such as enhancing creative content or tailoring voices to specific characters or scenarios, their value in real-time communication is less apparent. Apart from niche cases like salespeople using altered voices to improve their results, there is not yet a compelling, widespread reason for individuals to adopt such technology during live calls.

However, real-time speech AI solutions on the horizon show much greater promise for transforming communication. Some of the most exciting developments expected to gain traction in the coming years include:
- Real-time Accent Softening (an emerging trend)
- Real-time Voice Grammar Correction (a future trend expected the next 3-4 years)
- Real-time Voice Grammar Localization (a future trend expected the next 3-4 years)
- Real-time Voice Translation (a future trend expected the next 5 years)
These innovations are set to break down communication barriers, opening up new opportunities for individuals across the globe. By eliminating language and accent obstacles, these AI-driven tools can enable people from remote regions to connect more easily with others, allowing them to participate in the global economy more fully.
For instance, consider the potential of real-time accent softening. A person in India, speaking English, could have their accent automatically adjusted in real-time, making it easier for people in the United States or the United Kingdom to understand and engage with them. This could dramatically increase their employability in international markets, opening doors to jobs that might have otherwise been inaccessible due to communication barriers. When combined with other tools like real-time grammar correction or localization, non-native speakers can express themselves more clearly and confidently.
Another powerful use case for real-time speech AI is in assisting people with hearing impairments, cognitive decline, or those learning a new language. AI-enhanced communication can help these individuals better understand accents or dialects that they might otherwise struggle with, improving their ability to participate in conversations and stay connected with others.
Risks
Despite the promise of real-time speech AI, there are risks that must be carefully considered, especially in terms of privacy and security. One of the most significant concerns is the potential for scammers to use this technology to take advantage of others across the World.
To mitigate this risk, companies offering such solutions need to carefully screen customers and understand their use cases. Additionally, regulatory frameworks will likely need to be established to govern the ethical use of such technologies, ensuring that real-time voice enhancements don’t lead to widespread deception.
Challenges
The creation of real-time speech systems presents far more complex challenges compared to offline models. For real-time applications, AI must process and respond instantly to live audio inputs, which are often of suboptimal quality. Achieving this requires sophisticated algorithms capable of delivering natural-sounding speech in real-time, with latency being a critical issue. In offline settings, AI systems are typically tasked with converting pre-recorded speech, often using high end equipment, allowing for greater computational flexibility and higher accuracy since they are given a richer input, and aren’t bound by real-time constraints.
So a major challenge for real-time speech AI is managing the quality of input audio. In environments such as call centers, where background noise is common and agents may use low-quality headsets, the system needs to perform complex audio enhancement before it can accurately process speech. Poor input quality can drastically reduce the accuracy of AI-generated outputs, leading to misunderstandings or awkward communication. In contrast, offline systems usually work with clean, high-quality recordings, allowing for more precise voice synthesis.
Another challenge with real-time speech AI systems is there is no opportunity for post-processing. Unlike offline systems, targeted at creators, where AI has the luxury of refining and perfecting the output before it’s presented, real-time solutions must deliver immediate results. This means the generated voice needs to consistently sound natural and clear, even in unpredictable, noisy environments. The system must handle dynamic changes, such as background noise, diverse accents, and inconsistent speech patterns, all without the benefit of editing or re-recording.
As these obstacles are overcome, real-time speech AI is poised to play a pivotal role in bridging communication gaps, opening up new global opportunities, and transforming the way we interact with one another across linguistic and cultural divides. The vast majority of real-time, person-to-person online voice communication will then benefit from AI enhancements.
Conclusion
As real-time speech AI technology advances, it is poised to fundamentally transform global communication, making voice interactions more accessible, efficient, and inclusive. Today, the majority of AI-driven speech applications remain in non-real-time, recorded settings, primarily benefiting content creators, media, and entertainment industries. However, as latency challenges are overcome, real-time applications are on the horizon with far-reaching potential.
Emerging use cases, such as real-time accent softening, grammar correction, voice localization, and even live translation, hold the promise of breaking down communication barriers and enhancing mutual understanding across linguistic and cultural divides. These advancements can empower individuals from diverse regions to participate in the global economy, bridge accessibility gaps, and foster more inclusive workplaces and social interactions.
Nonetheless, realizing this vision is not without significant challenges. Building real-time AI systems demands instantaneous processing of live audio, often in suboptimal conditions with background noise or low-quality equipment. Privacy, security, and ethical considerations are also paramount, as this technology could potentially be exploited if not carefully managed.
As the technology matures and these obstacles are addressed, real-time speech AI will become a vital tool for enhancing human communication. By making speech more intelligible and reducing language and accent-based barriers, speech AI solutions will open up new global opportunities and forever change the way people connect, collaborate, and interact.
