This introduces a new challenge to dubbing workflows \u2013 <a href=\"https:\/\/www.ibm.com\/topics\/ai-hallucinations\" rel=\"noopener\" target=\"_blank\">hallucinations<\/a> \u2013 instances that create nonsensical outputs. Caddigan explains, <strong>&#8220;Generative models are simply predicting the next token (words), given what it&#8217;s already seen. Most of the time, this produces an accurate result. Sometimes, though, it spits out gibberish, so it&#8217;s always wise to have a human review generative results.&#8221;<\/strong><\/p>\n<p>Machine translation also struggles with regional terminology and brand-specific tone and language. Furthermore, the translated text must match the timing of the original speech, a task current MT models cannot accurately perform.<\/p>\n<p>Caddigan notes, <strong>&#8220;Current Machine Translation models are not capable of producing translations that synthesize to a specific duration,&#8221;<\/strong> resulting in translations that are too long or too short. We\u2019ll talk more about this challenge in the next section.<\/p>\n<h3>Synchronizing Dubbing with Speech<\/h3>\n<p>Timing is critical in dubbing and ultimately impacts the overall viewing experience. The translated text must match the timing of the speaker&#8217;s mouth movements as closely as possible, otherwise, it won\u2019t be enjoyable to watch. For example, if the speaker talks for 2 seconds but the machine translation creates a 3-second translation, the timing will be off and the viewer will notice.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.3playmedia.com\/wp-content\/uploads\/2024\/08\/212-300x300.jpg\" alt=\"\" width=\"300\" height=\"300\" class=\"alignright size-medium wp-image-34798\" srcset=\"https:\/\/www.3playmedia.com\/wp-content\/uploads\/2024\/08\/212-300x300.jpg 300w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/2024\/08\/212-600x600.jpg 600w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/2024\/08\/212-150x150.jpg 150w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/2024\/08\/212-768x768.jpg 768w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/2024\/08\/212-585x585.jpg 585w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/2024\/08\/212-700x700.jpg 700w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/2024\/08\/212-75x75.jpg 75w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/2024\/08\/212-165x165.jpg 165w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/2024\/08\/212-220x220.jpg 220w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/2024\/08\/212-174x174.jpg 174w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/2024\/08\/212.jpg 1000w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n<p>With a human involved, they can intervene and re-translate to better match the timing of the original audio. Caddigan highlights, <strong>&#8220;At 3Play, we have tools that help us resynthesize segments to ensure proper timing alignment, but AI-only systems only do one pass&#8221;<\/strong> which significantly impacts synchronization results.<\/p>\n<p>Direct translations from English to other languages can result in a 20-30% increase in spoken content (when translating English to German or Spanish for example). AI-only dubs either need to speed the content up to unnatural levels, force a misalignment, or some combination of both. However, with a HITL solution, the segments get re-worded to preserve alignment and tempo.<\/p>\n<h3>Speech Synthesis<\/h3>\n<p>Speech synthesis technology has seen significant advancements, producing high-quality outcomes most of the time. However, there are limitations when using synthesized speech technology. Caddigan explains, <strong>&#8220;Some percentage of segments will sound unnatural due to the nature of some generative AI models.&#8221;<\/strong><\/p>\n<p>These language models may also mispronounce words, requiring phonetic spelling adjustments to achieve proper pronunciation. Caddigan emphasizes, <strong>&#8220;You should expect some number of &#8216;synthesis errors&#8217; after an AI-only dubbing run, based on the length of content. Each speaking segment has some probability of unnatural, garbled, or mispronounced speech. Multiply that out by the length of your content and that&#8217;s how many errors you&#8217;ll have &#8211; it&#8217;s just math.&#8221;<\/strong><\/p>\n<p>In a self-serve tool, for instance, users must review each segment of speech and rerun the AI speech model as needed. In contrast, a HITL dubbing solution ensures that someone is overseeing the quality of the synthesized speech outcome, meaning you don\u2019t have to conduct quality checks yourself (saving you time).<\/p>\n<h3>Voice Matching<\/h3>\n<p>Voice matching is a new technique in AI dubbing where speakers&#8217; voices are matched against a large database of voices, making it <i>seem<\/i> as if their voice was cloned. In an AI-only system, the AI must guess how many speakers there are and precisely at what times they&#8217;re speaking.  It then &#8220;matches&#8221; their voice from these audio samples. Currently, this process is highly error-prone as AI models are not good at speaker <b>diarization<\/b> &#8211; an automatic process that segments an audio recording into distinct sections based on the identity of each speaker.<\/p>\n<p>This leads to several pitfalls.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.3playmedia.com\/wp-content\/uploads\/2024\/08\/213-300x300.jpg\" alt=\"\" width=\"300\" height=\"300\" class=\"alignright size-medium wp-image-34799\" srcset=\"https:\/\/www.3playmedia.com\/wp-content\/uploads\/2024\/08\/213-300x300.jpg 300w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/2024\/08\/213-600x600.jpg 600w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/2024\/08\/213-150x150.jpg 150w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/2024\/08\/213-768x768.jpg 768w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/2024\/08\/213-585x585.jpg 585w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/2024\/08\/213-700x700.jpg 700w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/2024\/08\/213-75x75.jpg 75w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/2024\/08\/213-165x165.jpg 165w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/2024\/08\/213-220x220.jpg 220w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/2024\/08\/213-174x174.jpg 174w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/2024\/08\/213.jpg 1000w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n<p>Caddigan explains, <strong>&#8220;If the model identifies the wrong number of speakers, it will blend voices and two speakers will be assigned the same voice.&#8221;<\/strong> This will confuse the viewer in the result &#8211; especially if two of the blended speakers are speaking to each other.<\/p>\n<p>3Play\u2019s HITL dubbing process addresses this by speaker-labeling every speaker during the initial transcription. This ensures accurate speaker identification and clean audio clips during the voice-matching step.<\/p>\n<h3>Background Audio Extraction<\/h3>\n<p>Last, but certainly not least, let&#8217;s discuss another important step in the AI dubbing process \u2013 background audio extraction. Background audio extraction models have gotten quite good, but still produce noticeable artifacts at times (incorrectly identifying background audio as voice or vice versa). To ensure maximal quality, the best approach is still to provide clean speaker tracks without background audio and mixing in the background audio post-dubbing.<\/p>\n<p>In reality, not everyone is looking for the same end result or has the same inputs for dubbing. Caddigan emphasizes the importance of flexible workflow options in a HITL dubbing service that meets people where they are and considers their unique needs. <\/p>\n<p>Have separate audio tracks? Only have the combined source video? It&#8217;s crucial to find an <a href=\"https:\/\/www.3playmedia.com\/services\/localization\/ai-dubbing\/\" rel=\"noopener\" target=\"_blank\">AI dubbing solution<\/a> that will take whatever inputs you have to ensure the best quality result.<\/p>\n<h2><strong>Looking to the Future of AI Dubbing<\/strong><\/h2>\n<p>The advancements in AI have undoubtedly revolutionized the dubbing industry, providing tools that can significantly streamline the process. However, the limitations of AI-only solutions highlight the necessity of human involvement to ensure high-quality results.<\/p>\n<p>As Caddigan puts it, <strong>\u201cYou shouldn\u2019t expect the first time you do an AI-only dub to be \u2018right\u2019. There are just way too many variables. AI will get you close and lead to faster turnaround times, but you\u2019ll need a human touch to smooth over AI\u2019s shortcomings.\u201d<\/strong><\/p>\n<p>As the dubbing industry continues to evolve, the advancements in AI dubbing have brought significant improvements, particularly when combined with human oversight. AI is a powerful tool, but it works best in collaboration with humans, ensuring that the final product provides the quality that viewers want.<\/p>\n<h2><strong>The 3Play (Dubbing) Way: Combining AI with Human Precision<\/strong><\/h2>\n<hr \/>\n<p><center><\/p>\n<div\n  style=\"position: relative; display: block; max-width: 600px;\"><\/p>\n<div\n    style=\"padding-top: 56.25%;\"><br \/>\n    <iframe\n      src=\"https:\/\/players.brightcove.net\/31193522001\/rkYTwXQWM_default\/index.html?videoId=6350106150112\"\n       allowfullscreen=\"\"\n      allow=\"encrypted-media\"\n      style=\"position: absolute; top: 0px; right: 0px; bottom: 0px; left: 0px; width: 100%; height: 100%;\"><\/iframe>\n  <\/div>\n<\/div>\n<p><\/center><\/p>\n<hr \/>\n<p>In the evolving landscape of AI dubbing, maintaining high-quality standards is crucial.
