Prior art

To identify the most relevant prior art for US Patent 12412561, I would typically search the patent's file wrapper on the USPTO website for the "References Cited" section. However, direct access to the USPTO's Patent Public Search (PPUBS) or Patent Center to view specific cited references and their details is not available to me. The provided patent text itself does not list the "References Cited" section directly, but it does mention its own priority claim to "U.S. application Ser. No. 18/083,727 filed on Dec. 19, 2022, and entitled “Real Time Correction of Accent in Speech Audio Signals,” which in turn claims priority of U.S. Provisional Patent Application No. 63/297,901 filed on Jan. 10, 2022, entitled “Real Time Correction of Accent in Speech Audio Signals.”" These are important for understanding the patent's own lineage, but are not prior art in the typical sense of being external citations.

Given the constraints, I will proceed by treating the patent's own priority claims as the most directly referenced "prior art" within the provided document, understanding that these are internal to the patent family and not external anticipatory prior art from other inventors. For external prior art, I would need access to the USPTO's official "References Cited" section, which is not present in the provided text.

Based on the information available in the patent document itself:

Internal Priority Claims (which could be relevant for a 35 U.S.C. § 102 analysis if their content were publicly disclosed prior to the critical date of 12412561 and not covered by the grace period):

1. Full Citation: U.S. application Ser. No. 18/083,727

   • Publication/Filing Date: Filed on December 19, 2022
   • Brief Description: Titled "Real Time Correction of Accent in Speech Audio Signals". This is a continuation-in-part application from which US12412561B2 claims priority. It would likely describe a similar or foundational system and method for real-time accent correction.
   • Potential Anticipation (35 U.S.C. § 102): If the subject matter claimed in US12412561B2 was fully disclosed in US18/083,727 and the latter was published or otherwise made available as prior art before the critical date of 12412561 (and not subject to the inventor's grace period under 35 U.S.C. 102(b)(1)(A)), it could potentially anticipate some or all of the claims of US12412561B2. However, given that US12412561B2 is a continuation-in-part, it's more likely that US18/083,727 provides support for the claims in 12412561 rather than anticipating them.

2. Full Citation: U.S. Provisional Patent Application No. 63/297,901

   • Publication/Filing Date: Filed on January 10, 2022
   • Brief Description: Titled "Real Time Correction of Accent in Speech Audio Signals". This provisional application provides the earliest priority date for the family and would contain an early disclosure of the inventive concepts.
   • Potential Anticipation (35 U.S.C. § 102): Similar to the non-provisional application above, if the content of this provisional application was publicly disclosed before the critical date of US12412561B2 and not covered by the grace period, it could potentially anticipate claims. However, provisional applications are generally not published and typically serve to establish an early filing date for later non-provisional applications.

Note: The determination of "most relevant prior art" typically involves an analysis of all cited prior art references (patents, publications, etc.) by the examiner during prosecution, which are usually found in the "References Cited" section of the issued patent. Without that specific section, I cannot provide a comprehensive list of external prior art directly.
