“…Passive transcutaneous BCIs face limitations as the skin and subcutaneous tissue can attenuate the vibration (14,19). In comparison, active transcutaneous systems can transmit high-frequency sounds more efficiently (20). This is congruent with our results which showed excellent postoperative speech audiometry and improvements in speech reception threshold.…”

“…Mylanus et al showed significant improvements in speech recognition and patient-reported outcomes following Osia implantation compared to the patient's Baha Softband (14). Another recent prospective trial by Pla-Gil et al compared Osia to Baha Power Connect found comparable performance in speech recognition (20). The Osia system was found to have greater mid- and high-frequency gains compared to the control group (20).…”

Objective:To describe the early surgical and audiometric outcomes in pediatric patients implanted with a new active transcutaneous bone conduction implant system.Study Design:Retrospective case review.Setting:Tertiary pediatric hospital.Patients:Pediatric patients (18 or younger) with conductive or mixed hearing loss that completed postoperative aided testing following implantation with the Cochlear Osia system from December 2019 to December 2020.Intervention:Rehabilitative.Main Outcome Measure:Preoperative air conduction (AC), preoperative bone conduction (BC), and postoperative aided thresholds were compared. Pure-tone averages (PTA), air-bone gap (ABG), and functional gain were calculated. Surgical complications and patient satisfaction were summarized from the chart review.Results:Sixteen patients (20 implants) met the inclusion criteria. The average age at the time of implantation was 12.9 ± 2.4 years. The preoperative AC and BC thresholds were 64.4 dB (±11.9 dB) and 7.9 dB (±4.90 dB), respectively, with an average ABG of 56.5 dB (±12.8 dB). The average postoperative aided threshold was 21.2 dB (± 4.25 dB) with a mean functional gain of 43.1 dB (±10.2 dB). One patient developed seroma postoperatively, which was treated conservatively. No other complications were reported over a mean follow-up time of 7.1 ± 4 months. For 13 patients with previous passive bone conduction implants or devices, the Osia system was universally favored.Conclusions:The new active transcutaneous bone conduction system showed favorable early clinical and audiometric outcomes. Repeated processor connectivity issues represent a potential area for future device development. This is the largest pediatric case series to date.Level of Evidence: Level 4—Retrospective Review.

“…Osia does also provide a benefit for speech recognition in noise [ 4 , 8 ]. Subjective evaluation using the SSQ, APHAB, and HUI showed benefit for Osia recipients [ 8 , 11 – 13 ], and our long-term data revealed the largest benefit at > 36 months of Osia experience.…”

“…Gawecki et al (2020) showed higher speech recognition scores as well as larger self-reported QoL with the Osia compared to the Baha Attract [11], while Pla-Gil et al (2021) compared a control group of ten patients using a Baha 5 Power Connect with a group of 10 Osia 1 patients and found a comparable hearing performance in terms of both audiological and subjective outcomes [13]. As a consequence, Osia can be regarded as similarly effective treatment to other percutaneous BAHS with the highest audiological output, and as superior to other transcutaneous bone conduction devices (Ellsperman et al (2021) provided an overview [14]).…”

Purpose The new active transcutaneous partially implantable osseointegrated system Cochlear™ Osia® System is indicated in case of conductive or mixed hearing loss (CHL/MHL) with a maximum average bone conduction hearing loss of 55 dB, or in single-sided deafness (SSD). The implant directly stimulates the bone via a piezoelectric transducer and is directed by an external sound processor. We conducted a monocentric retrospective longitudinal within-subject clinical study at our tertiary academic referral center. The aim was to investigate long-term data (2017–2021) on audiological outcomes and hearing-related quality of life for the Osia system. Methods Between 2017 and 2020, 22 adults (18: CHL/MHL; 3: SSD) were implanted with the Osia100 implant; seven received bilateral implants. As of 10/2020, the sound processor was upgraded to Osia 2. Results Mean Osia system use by 04/2021 was 30.9 ± 8.6 months (range 17–40 months). Unaided bone conduction thresholds were unchanged postoperatively. One patient had to be explanted because of prolonged wound infection. Aided hearing thresholds were significantly lower compared to the unaided thresholds preoperatively, along with a marked increase in speech recognition in quiet. Speech processor upgrade resulted in a stable benefit. Patients with CHL/MHL and SSD showed a similar improvement in self-rated hearing performance revealed by SSQ, APHAB, and HUI questionnaires. Conclusion The Osia system is a safe, effective and sustainable option for treatment of conductive and mixed hearing loss or single-sided deafness.

“…In the software, quantize the audio signal and preemphasize the processing, calculate the ratio between the frame shift distance and the length of each frame, obtain the analog signal conversion frequency and the basic unit quantization index, construct the speech text decoder based on the continuous hidden Markov model, calculate the width of the window function, obtain the Markov chain probability path in the grid, compare the complexity of different probability paths, design the English translation robot speech recognition algorithm, and get the speech recognition results of English translation robot. From the experimental data, it can be seen that the speech recognition accuracy of this system is above 75% under three different audio qualities, which is more stable than other systems, and the accuracy is higher under the same audio quality, which shows that the speech recognition system with the continuous hidden Markov model is better than other systems [21].…”

Speech recognition plays an important role in the field of human-computer interaction through the use of acoustic sensors, but speech recognition is technically difficult, has complex overall logic, relies heavily on neural network algorithms, and has extremely high technical requirements. In speech recognition, feature extraction is the first step in speech recognition for recovering and extracting speech features. Existing methods, such as Meier spectral coefficients (MFCC) and spectrograms, lose a large amount of acoustic information and lack biological interpretability. Then, for example, existing speech self-supervised representation learning methods based on contrast prediction need to construct a large number of negative samples during training, and their learning effects depend on large batches of training, which requires a large amount of computational resources for the problem. Therefore, in this paper, we propose a new feature extraction method, called SHH (spike-H), that resembles the human brain and achieves higher speech recognition rates than previous methods. The features extracted using the proposed model are subsequently fed into the classification model. We propose a novel parallel CRNN model with an attention mechanism that considers both temporal and spatial features. Experimental results show that the proposed CRNN achieves an accuracy of 94.8% on the Aurora dataset. In addition, audio similarity experiments show that SHH can better distinguish audio features. In addition, the ablation experiments show that SHH is applicable to digital speech recognition.
